Harold,
Who is Harold Brookshire? This is who my engine builder dealt with both at UD and at General Kinetics.
Is he confused? Or am I confused?
Ron

Harold Brookshire is UDHarold.

I just realized that I have been confusing Harold Sutton with Harold Brookshire.
Harolds.......my apologies.
Ron

Ron,

Don't apologize....I sometimes think threads for him were meant for me, too...
Since you asked, I'll give everyone a very very short history of me, so you'll know where I came from.
1969---Went to work for State of Mississippi as computer operator, rose to be lead operator at CDPA, Central Data Processing Agency.
1972---Began working on cam design program in my spare time.
Dec 15, 1972---Sold 310AP SBC solid to Reed Cams, Georgia, for $125.00.
1973---Made $3000 selling to Reed, Isky, Engle, Norris.
1974---Designed Reed's RxxxULX line of rollers, and a lot more, including Benny Parson's 1975 Daytona 500-winning cam. Also Shirl Greer's TF/FC NHRA National Champion Nitro Funny car cam, designed for Norris, and it was a True Chrysler flat tappet, with .438" lobe lift.
1974---Became General Kinetics' cam designer, worked with people like Bill Jenkins and Jack Roush on the cams for their ProStockers.
1976---Jenkins wins Pro Stock Natinal Championship, with GK doing large-barrel cams.
1977---I start in January with Competion Cams, as their original cam designer. Over the next 3 years, I design them hundreds of cams, including the 268 High Energy. I introduce them to the unsymmetrical cam.
1979---I write them their 1st in-house cam design program. Before that, we shared a program with Cam Dynamics.
1980---After negotiating since late 1976 for some stock ownership in Competition Cams, I leave and start UltraDyne on April 1st, 1980. The 1st month I design the 288/296F5 and the 288/296R6, the 2 most popular cams I ever made.
1981---In September, I hire my 1st employee, Mike O'Neal, who ran my shop, made all my models and masters, etc.
1982---We're running 2 shifts, from 7:00 AM to 12:00 PM. Tim Goolsby comes to work for me, he is Mike's brother-in-law. I also design UltraDyne's first hydraulic cams, such as the 272, the 276, the 288/296H.
From then on until 2000, we all just worked. UltraDyne grossed over $1.2 Million a year from 1990 to 1999.
2000---A number of independent factors began to take their toll---Federal Mogul acquiring my 2 major solid lifter core manufacturers, and their later Chapter 11, Lifter companies disappearring, tremendous cash-flow problems in the end of 2000, initially triggered by the UPS strike---We lost around $50,000 in the strike.
2001---A un-named cam company in Memphis hires 8 of my 12 employees, and 2 more just leave because they think --that's it. Only Tim and Gail are left with me.
2001-2003---UltraDyne is in the Chapter 11 'Death Spiral'. I take a $0 salary for 2002, and pump all my, and my wife's, retirment money into UltraDyne, along with all the equity I could get on my house, etc, etc, etc.
June 2003---Everything is gone, the government locks the doors.
August 2003---I go to work at Lunati, charged with completely re-doing their entire line of cams. Mike is already there, waiting for me, along with Steve Slavik, who worked for me for 13 years (Mike for 19...). Then I meet the corporate world.....
Oct 2004---Lunati introduces the VooDoo cams. And they really work good.....

This has been the line and times of a cam designer, and even with the down sides, it has been the time of my life, and I'm going to stay at it as long as I can.....

No comments are necessary, you are all a great bunch, and as that Great American, Minnie Pearl, said, "I'm just so proud to be here!"

Thanks,

UDHarold

Shazam Harold! Wow what a history and sure you could tell some woppers around a campfire hey?!
My next engine will have one of your cams! Keep up the good work at Lunati! graemlins/waving.gif

Well Lunati made at least one more sale by picking you up.

I selected a Lunati hyd roller for the new engine for my truck, it is probably a shelf grind that existed before you, but I bought from them simply because I am impressed by your integrity and honesty and I like to support the company you now work for so you can hope for a good retirement one day.

Cheers to you Harold. graemlins/beers.gif
When I'm ready , Lunati for me too.
Mitch

so you DID have something to do with the VooDoo cams?
are they really as cool as the skull and crossbones logo they use for them?

Harold, I will be changing the cam in my 502 sometime in the future and I can guarantee you (Lunati) will get the sale. I'm incredibly impressed by your willingness to help the guys on this site with any/all of their questions and your wealth of knowledge is humbling! You are one of the reasons for the success of this site. I just figured a thank you was in order.

Tom

And I might add...
Harold is a heck of a nice guy to have a conversation with on the phone. A true pleasure!
His wealth of knowledge and willingness to share that expertise overwhelms me. graemlins/thumbsup.gif
Thanks Harold.

Harold,
Thanks for the wealth of information you bring to this board. I'll be posting one of those 'cam selection' posts soon, so I can decide which Lunati cam to buy.

Thanks again!

I don't know if I would have that kind of fortitude, honestly. graemlins/beers.gif to Harold.

Thank you Harold!
Glad you are still here and doing what you love.
I'll share this with Larry Kalsch my engine guy.
Ron

I'm building my 427 around one of his 276/284 solids. I think I have one of the last Ultradyne cam boxes around! I can't wait to get it running and I will proudly preserve that box.

I only wish I had an Ultradyne sticker to add to my show sign which will feature stickers of all the products I'll use in the wagon build.

Harold's willingness to share his knowledge and his obvious honesty is why my BBC has a Lunati CAM in it now. (276/284 Solid) It really is a great CAM. Sounds good runs great. As soon as I can get my butt back to the track with my new converter, We will see what she'll do in my heap.

Thank you Harold!!!!

I always enjoy reading UD Harold's posts and his name is REAL easy to remember too. :D , Harold Sutton

Jerry

Ozrod,

As that famous American said, "It all depends on what you mean by 'input'!".
Did I argue with people at Holley about what the cams should be, and especially the name?
You betcha!
Are the VooDoo lines the last word in hydraulic cam design? Not really, I did mild them down a lot, and the solids, and the hydraulic rollers, and ALL the .904" tappet Mopar designs. The lift is quite low over what it could have been.
Did anybody actually HELP me design the profiles on the computer? No, of course not.
I know of no one, at Lunati, Holley, or Comp Cams, that really understand cam design. If they did, would cams be designed that way they are?
The VooDoo cams aren't being manufactured the way they should, but that'd because no one believes we'll sell as many as I think we will. They are being made accurately.
My name was " INTENSE TORQUE , and such solgans as "Let Lunati put IT in your engine." or "Tell everyone, when your car picks up, that you got IT from Lunati."
Oh, well, that's the corporate life....
UDHarold is solely reponsible for selection and design of opening and closing ramps, peack acceleration and veloicty rates, nose acceleration rates, offset, and anything else you could think of in regards to cam design.
The same is true of the VooDoo solids, hydraulic rollers, street rollers, and other series such as the S/S series and the Super-K series.
I just need to get all these masters made. I have over 100 of them waiting in line.....

UDHarold

BTW, thanks, everyone, for all your kind words. I was not trying to solict them, but they did an old guy good.....

harold,
your an american icon.
i use your cams also.
i want to thank you personally for kickin asss all those years and what u brought to the table.
When all the old guys are gone that just leaves us younger guys [ 43].
we need to muscle up.
us younger guys.
thanks again!!!!!!!!
jk

Tell those corporate guys to use spell check! At a glance, I counted three errors on this page.
http://www.holley.com/VoodooCams/ProductInfo.htm

You mentioned lifter manufacturers. I managed to find some old Johnsons for my GTO. Are these the good ones? I figure there's definately a market for KNOWN GOOD lifters. Hint, hint. ;)

Spoke with Harold at length regarding a Cam for
my brothers 383. What a pleasure to to work with.
Very impressed by the 267/275 solid he spec'd.
Put a 276/284 solid in a 408 Pontiac recently.
Awesome sounding/performing product.

Harold you are a real asset to the Industry.
Hopefully Lunati/Holley realizes that.
When are the Voodoo BBC stret rollers coming out?

Thanks Harold

Yeah I counted 3 errors also. Hmmm, at least there's one guy at Lunati that knows whats going on... UDHorold that is ;) .

There are some great people working for Holley. I've had the pleasure of meeting some of them such as Doug Flynn in person. Haven't met Harold yet, but maybe when I head up to Bowling Green again in May.

But I guess corporate management is the same wherever you go... The sign of a good engineer is how well he ignores management. :D

/Markus

I know of no one at.... Comp Cams, that really understand cam design.:eek: Yikes! That is a pretty bold statement about a major competitor. Lots of people with cars running well on Comp designs... how bad can they be? :confused:

UDHarold,

You are a LEGEND! I never knew the history or experience behind you. It's no wonder everyone wants your opinion. I dont know what my generation would have done without you.

If they aren't everything you think they could be, would you ever release a version that would? smile.gif

I know for sure the Very popular Comp Cams 268H is his design, and I believe the rest of the High Energy series of cams?

So at somepoint, at least one person at CC knew what they were doing, but he doesn't work for them anymore, lol.

I'm an old codger, and sometimes I say what I think. I apologize to all the Comp Cams fans that I offended.
Getting back to what I can talk about, there are VooDoo solids designed, starting about 223° at .050, .468" valve lift, and going up in size. Which ones will be offered in large quantities, vs special-order, is still being debated, and dyno tests have not yet been done. Some of the cams have been awaiting dyno-tests since August.
I have also designed a series of RACING solids, ranging from 238° at .050", about .500" valve lift, up to cams in the 280's at .050", and lobe lifts over .400". These all have the same ramps, etc, and cover from 350 cfm 2-bbl oval engines to Dominator-equipped BBCs running in the 9s.
We are debating when I can make the masters and release them.
Right now we are setting up to dyno-test the 3 VooDoo hydraulic rollers we have at Bowling Green, and I am working on the Street Series of VooDoo solid roller cams. I have the 6 profiles designed, and am in the paperwork stage now.
I would like to have everything released within the next 3 months, but I cannot gaurantee it.
When they are finally here, you all will like them......

UDHarold Now here's the part I'm interested in. Looking forward to the dyno results and full specs.

/Markus

UD Harold, I've tried calling you but couldn't get through. I need some advise on a big roller cam thats going in my sons shootout motor. I'll try you again at Lunati whenever it's most convenient for you. Just suggest the best day and time a little ahead of time.

Incredible life story Harold. Sad to hear you & your wife had to use up your retirement $$. Hopefully you got a good deal at Lunati. Good Luck. graemlins/thumbsup.gif

Harold,

I rarely pick up the phone, as I'm up to my ears in engineering paperwork and cam design. I can not be interuppted while I'm designing, destroys my chain of thought.
Tell Amy your name and phone number, and I will call you when I can, the same day.

UDHarold

UD Harold, I'll try you again in the next few days, I know you don't have a lot of time and i don't want to complicate your already hectic work schedule. I had a parts store once and understand busy.

ttt, just so new people know who udharold is and what he is all about. Everytime I read his story it inspires me, he is truely a great person to have on this site. His dedication to cam design and his willingness to explain some of it to us is amazing.

Hey UD, weren't you also in the Army?

Wow, you're really going back.....
Of my father's 9 sons and grandsons, 6 of us ENLISTED!
I spent 60 months overseas, re-enlisting for the Cuban Missile Crisis. 22 months in Turkey, 38 months in Germany. I worked all my 2 tours overseas for NSA and had a Top-Secret Crypto security clearance. I still maintain my membership in AUSA, the Association of the United States Army. My baby brother spent 2 1-year tours in VietNam. Our half-brother retired as a Major after 20 years in. My son joined the Marines while a senior in high-school--He is now grinding 'specials' down at Crane, as Lunati has a no-relative policy. My baby brother's oldest son spent 3 years in Bosnia, and is now a civilian analyst in Baghdad. His brother was a Marine involved in the invasion of Iraq and the drive to Baghdad.
I suppose we must be those Southern Scot-Irish you hear about.......

UDHarold

BTW, I was also a good dancer in high school and pretty good as a street racer, 57 Chevy Bel-Air, 4bbl with wide-ratio 3-speed and 3.7 rear gear....

We got onto the subject of Military Service when I told you why I was changing the cam on my 502. I just got back from Iraq and wasn't going to put up with the wussy cam GM installed in my crate motor.
Anyway, I changed the compression(13:1), heads(canfield), and intake(victor) since then and now need another cam. My engine builder wants me to use something with about 267 intake at .050 and about 275 at .050 exhaust and about .750 lift on a 110 sep with an intake center line of 106. Got anything like that? Roller of course.

kstanbach,

I have a cam almost identical, either .759" or .750" gross valve lift, that I can make only as a CNC cam grind----No physical masters yet. But over the past 2 weeks I helped get the CNC grinder to work with new cam grinds, and they look perfect.
I will be tied up all day Monday in meetings, and have to go to 'Excell' school on Tuesday. Call me Wednesday or later and tell Amy to let me know you're on the line.
Let me know what compression your engine is.....
You will need a 4000-4500 stall converter.

UDHarold

Harold, hello from Glen Shepard and Chuck in Birmingham...Question, what cam for a 331 SB ford for a street/road race Mustang???? PS have UD276/286 in current 351c and most happy ...thanks

Harold,

Ol' pdq67 here!

Please sit down and do no more than dictate onto a tape your story so that it can be put into printed word like Mr. Crane has done so the pup's will know it!

Hell, send the tape(s) to me and I will type it into a word doc for you AND I'd love to!!

You really owe it to all your fans and to yourself and wife to do so....

pdq67

Thanks again for my cam Harold Its awesome ! :yes:
In a tank with only a 3000 stall,less then 10.1 compression,and mild 342 gears In 80 degree weather it runs 10.5s all day.
Hydraulic roller. Mild 111 lobe sep.
When I go to a more of a drag race suspension it will run low 10s all day.
I had one of your ultradynes in my 406 it to was fast for what it was.
It ran 11.41 @119.7 with a 1.67 60 ft with 323 gears @ 3650 pumpgas NA.
My dad (Big red L-72) bulit a pumpgas 534 that ran 9s with one of your hydraulic roller cams.
Hes built 1/2 dozen motors with your cams in the last few years ALL of them ran great ALL of them were 2-3 tenths quicker then similar combos
even with less compression,gears,and stall.

I like digging up old threads here and there......

I like digging up old threads here and there......

ha i forgot about this one.

all im going to say is..
i run the 60122 voodoo hyd roller in my 355.. and...
my heads are not big enough for this cam.. haha.

sounds great, runs great.. and we will see how much it likes the spray.

thanks for your work man, if it wasnt for you on here or at lunati,, i probably would not have bought this cam.

"Bullet cams, the new home of Ultradyne"

What's the deal on Bullet cams?
Is it Harold's or somebody else's?

Someone elses, with his old designs, and some of their own. None of HIS current stuff.

I feel good having an actual UD cam in my motor, Lunati produces the same design now, but I still have the UD box sitting around somewhere!

I have a bit of a history question for Harold if he worked on the Norris cams back in the late 70s .

I had a BBC 454 with a Norris Racing Cam grind number 387. (dont ask me how I remember that) I have no Idea of what the specs on the cam were but it was by far the best cam I ever had in a motor at the time. I would to love know what the specs were if anyone could help me dig that info up.

I know he left Lunati and Bullet. Who does he work for now?

Hadn't heard that he left Lunati....

I know he left Lunati and Bullet. Who does he work for now?

He never worked for Bullet. Here (http://www.chevelles.com/forums/showpost.php?p=1311573) is a good history from 2005.


Post #4 in this thread gives history till 2005.

He does design cams again for Lunati.

HERE (http://www.chevelles.com/forums/showpost.php?p=2272008&postcount=23) is a post from last year talking about it.

Yea your right. My mixup. I go that idea because Bullet has his Ultradyne logo displayed. Ultra turned into bullet right?

I thought he was working for a small place now?

Still have an original 288/296 hyd flat tappet big block cam, 231/239 @.050" .550"/.575" 110° lobe center

In looking through my way-back records, the work I did for Norris was early to mid-1970s. I found a lot of Reed and Engle cams though.
Call 818-780-1102 and see in Chuck Baronian is around. He was running Norris Performance Products after his uncle Norris died. He should be able to give you the specs on the 387.
I still work with Lunati. I am currently doing a group of lift-rule cams for oval track for them, and back in October I did a lot of high-lift LS1 hydraulic rollers for them. A lot of .625"-.650" valve lift cams, for use with their new Beehive springs.
I never worked with Bullet Cams, they just bought UD after it went under.
However, Tim Goolsby works there, and he worked for me 21 years at UltraDyne.

"I still work with Lunati".:yes:

WWOOOOO WWHHHOOOO, Its the GOD of cams. I purchased one of your voodoo cams and will finally have a chance to install it this weekend. Cant wait to put a lil magic on the road. "I still work at Lunati". Yes!!!! and the guy named Steve there is also GREAT help also. What a guy he is.

BTW, you are one tough guy to get in contact with.

Steve was one of Harold's original employees...
