Looks like the kind of thing I'd use. It has a lot of lift without going too nuts on duration. I also like the 110 LSA. It should make a lot of power and still be streetable. We'll be looking forward to hear how it works in your combo.

Bob,
Have it custom ground on a 107LSA

Depends on what you are doing with it.

Also the -8 cams are cast not billet & the kit probably comes with the Endurex lifter.
I won't print my opinion of the Endurex lifters except to say I do not use them in anything.
Get the cam custom ground on a billet with the cast gear option & use the best lifter you can buy. I would suggest the Isky Red Zones which I can probably save you a few dollars on if your interested. ;)

street/strip.

I agree completely about the lifters!

That cam looks familiar ;)
Bob,looking for high 10's/low 11's ? smile.gif
I'd love to get the 2.19/1.88's installed in my 215's and use that cam in my 454,along with some 3.55's or 3.73's graemlins/thumbsup.gif

thats what I'm hoping for Chris,,,is the billet core for longevity? are comp springs,retainers and locks okay to use...just not their roller lifters??? thanks guys graemlins/thumbsup.gif

Seany likey! Nice seperation between duration and lift. That cam looks like it has looowwww 11 written all over it! Now you've got me rethinking my cam choice.

you need to have the springs picked out for the average seat/open pressures you're looking for based on what your installed heights are.

Springs are one of the last things you buy.

I believe you, but if you're me then you're looking at 11.5x, cuz I can't get a 60' to save my life. :D

I beleive racer's cam was bigger, 248/252 ???

Looks like a dandy cam!

You think it would be better than a Lunati 502A3 245/253@.050, .660/.660 on a 108 lsa/102 icl?

Since you've had good luck with Lunati, that is. After reading posts here, and talking to the local bbc guru, Isky Red Zones seem to be preferred by pros.

Anyway, hope you go through with it. $1000.00 " Attsa lotta clams!" but if you get anywhere near a 10.99 it'd be worth every penny.

Bob, check your mail.

LOL,
That's pretty much what I have in the 505 Bob.
I had it ground on a 112 LSA for sleeer idle quality.

As previously mentioned, do NOT get it shelf stock. It is on an austempered iron core (cast iron) core. A roller should NEVER be ground on a cast core.

Comp does it because they are getting cores cheaper that way, they advertise it as using a stock distributor gear, etc..

The iron core rollers are not worth the risk. Do a search on the internet and see what the results are...

You can get a billet roller with a cast iron gear. This is the way to go. There are two major core suppliers making these cores. The one you want your core ground on is from Cam Machine. The material and quality of the gear they press on is top notch.
The other core type has the whole rear of the cam cut off, and a iron gear, rear journal area pressed on, and pinned. Nothing wrong with this method but the normal cam gear quality is about a 3-4 on a scale of 1-15. 15 being Perfect. The Cam Machine gear is in the 10-11 range.


Isky Red Zones are good but at ~$700 a set last I heard I went with a Crower Severe duty with HIPPO. $430.

Comp springs, retainers, locks are fine.

I chewed a distributor gear on the 505 and called Comp to see about getting the cam repaired.
They were less than helpful so from now on I will be doing business elsewhere.

I had the cam repaired by Delta Camshaft of Tacoma, Wa. They can also grind you a custom cam for less than just about anyone else. I've been dealing with them for years. Gotta say I've had great lick with them everytime. They picked up the slack on the Comp Cam...

And they are a Comp cam dealer, grind with Comp Cam masters, have over 5500 masters to choose from. But you have to call them..
No fancy catalog, no fancy box...

If you are dragging this ride (your car?) I'd close up the LSA on that cam...

Email me if you need any advice. i can prolly save you a headache or two... BTDT.

Oh yeah,
the Crower lifters use stock length pushrods...

I purchased my Red Zones from Ron Iskenderian at Isky about a year ago and got them for $465.

Ron told me that the Crower Servre Duty (with HIPPO) and the Isky Red Zone lifters were very close in quality and strength. The big difference between the two is that the Isky's are rebuildable and the Crowers are not.

Mike Lewis (Wolfplace) I believe is an Isky distributor and can probably get them to you for a good price.

Bob,

That cam looks like it would make killer mid-range torque. I have been considering that cam if I ever replace my Isky roller. (My cam is a street roller of old design with pretty gentle ramps)

Have it ground on a billet core with a cast gear and a 108 degree lobe sep. Use the Isky Red Zones and a good set of springs. I have also heard very good things about Isky's Endurance line of springs.

I would think that this setup would get you low, low 11's. graemlins/hurray.gif graemlins/thumbsup.gif

Bob,
before you make your crower order, call me, my email is offline until sunday night.

I misplaced your number Brian and didnt write it in the phonebook graemlins/clonk.gif I talked to Ed yesterday,got the serial number for the cam,#'s for springs,retainers and 10* locks. Email the number when you get back online,I'll give you a call graemlins/thumbsup.gif

Quite frankly i didn't find the roller cams that much quicker or faster in my sons 482 BB. Lots of extra money for nothing. The car ran 10.48 with the small roller( Crane 268/272 and .714 lift) vs. 10.49 with the (ZL-1 grind with 1.8 roller rockers on the int. .600 lift and 262/273 duration). The flat tappet had more mid range power than the roller and actually ran more speed 128-127.

The findings in my friends ride have been much different, and his is the closest example that can be made to what Bob wants to build.

He's going to use a cam that proved to ET well in the combo it was used in.


What were the lobe seperations on those to cams, and where did you install them?

Did you make other changes? Many people do the roller swap when they're having the motor freshened, and often change more then one thing.

Not to mention that ET's swing roughly 3 tenths in most cars over the entire season.

Called Comp and ordered the cam today,
654/661
@50 248/254
@200 170/176
lsa 107
slightly larger than the shelf grind(in the link) with tighter LSA...hoping for good things...billet core,cast iron gear...two days and its in the mail smile.gif
