As we know Comp now owns Lunati, what a crying shame. Anyways, does anyone have success trying to get a profile from Luanti anymore, like a Harold grind or something like that?
Lunati cams are gone, but wait, can you get a profile????

What about Bullet Cams? I know they have the Ultradyne master list.

Have you called to see if you can get a cam? I also want one of those as well as a couple of Solid Rollers.

I know they have some of Harolds stuff there, but unsure if they will release it or what not

A few years ago I had COMP grind a BBC solid roller for me using Crane lobes.
I went through a friend of mine who is a dealer and tight with COMP, I gave him the lobe numbers and COMP ground it--begrudgingly I might add--and it wasn't cheap.
It did make outstanding power on the dyno though, so there's that.
No, I'm NOT a fan of COMP -at all.

Bullet, Isky, Howards, Jones and Cam Motion all have great lobes and should be able to grind what you need. If I recall Howards has some lobes that Harold was a part of, or at least that’s been the internet rumor.
Last 3 cams I used were ground by Bullet, one was actually a regrind. I like how they identify lobe profiles, for BBC applications went with CRA lobes (conventional, rpm, asymmetrical). You just need to factor in the rocker ratio to calculate the lift, they only list the lobe lift.

???? Is this in reference to information on bad machining? Did I read and understand that correct?
Yes and in this industry/hobby the vast majority can't verify what they got and assume it is fine. We all know what happens when you Assume. Now on the flip side the vast majority don't need every ounce of power out off a build, BUT what if the lobe your checking is correct but another one is 10 degrees larger at seat and what if if the deck of the block is .017" higher on the one your checking compared to the one with 10 degrees more duration....What about P to V now?
My advice, if money is tight but you got time. Checking p to v on an engine at all 4 corners is time well spent.

We’ve had good very good luck when a certain person was still there.
My last one was for my turbos.
they spin them (2) so fast at idle they force air out of them.
I had to put a light spring in the BOV to let air escape!
This is with a 75mm exhaust wheel and 1.25 housings.
They will spin for 20 seconds after I shut it off.
journal bearings too!

Are you referring to Harold or Chase?
I've shared this before on here, and I get the impression it falls on deaf ears, ( or should I say on blind eyes) but I'll repeat it for the OP.....Forget about the Bullet cam company for anything with Harold Brookshire's lobes. "Why" you ask? Because I've spoken with two different cam techs over there, ( Chris Paget being the most helpful) and if they're completely honest with you, ( as Chris usually was with me) they will fully admit that at least half of their "Ultra Dyne profiles" are not Harold's designs at all, and among the ones that are, most of them have been modified long after Harold sold the Ultradyne company. And the cam tech guys at Bullet have no way of knowing which lobe profiles from Harold were modified and which weren't. So it's hit or miss at best trying to get a camshaft with a true lobe profile which was actually designed by the late great Harold Brookshire, ( AKA "UDHarold"). So put to rest the old rumor that you can actually get a cam with Harold's lobe profiles from Bullet cams. That simply no longer applies.
Howard's Cams: It isn't merely a rumor that Howards actually offers Harold Brookshire's lobe profiles. Howards Cam company purchased a cam grinding machine that the one and only Harold Brookshire used to use himself for grinding some of his custom cams for his customers. It had 104 of Harold Brookshire's lobe profiles stored in it's computer memory, and since then, Howard's offers those lobes. But here's the thing: don't expect the tech guys at Howards to know much of anything about those lobe profiles, and one guy over there is even adamant about trying to talk you out of choosing from that lobe list even though the Howards website has them right on there in a PDF file.
There is only ONE guy at Howards who knows anything at all about Harold's lobes located in that list. And that is Steve Slavik, and that's because Steve knew Harold very well, because he worked for him way back when Harold owned UltraDyne cams, and he worked with him at Lunati too. However, even Steve will not even make mention of the 104 lobes from Harold that Howards cams offers. He will only talk about if you the customer brings it up.
So to get a camshaft with Harold Brookshire's lobes, you have to do a custom order, ( it definitely won't be off the shelf at Howards Cams) and you first have to go onto the Howards website, and pick out your own lobes by yourself because nobody at Howards is going to help you make that choice, and like I said, at least one guy over there will actually argue with you about making such a choice, because even though he was never a cam designer himself, he's convinced that he knows better and knows more about camshafts than the late Harold Brookshire did.
So pick out the lobes you want first, ( if you believe that you have enough knowledge to do that, or you're willing to take a stab in the dark just to have a cam with Harold's lobes) and write down the lobe numbers you want, and then call Howards cams, and don't ASK the guy you're speaking with IF you can get a cam with Harold's lobes, but TELL HIM you want to order a custom cam, and you already know what lobes you want. That is the ONLY way I know of to really get a camshaft with Harold Brookshire's lobe profiles, and to my knowledge Howards cams is the last and only place you can get that from.
Go to Howards Cams website, and at the top of the page you'll have to click onto "DOWNLOADS"....once you're on the downloads page, click onto the second catagory titled "LOBE LIST" and you'll see a long list of lobe profiles. Scroll all the way to the bottom of that list where you'll see the last group titled "Flat Head Ford" and then scroll upward slightly to where you'll see the next lobe group titled "28 degree Major Intensity" and those are Harold Brookshire's most aggressive Mechanical roller lobes, and the next group upward from there is titled "31 Major intensity" which is also mechanical roller lobes for street and strip, but slightly less aggressive than the 28 degree lobes are. The next group upwards from that is a smaller group and is comprised of Harold's solid flat tappet, and Hydraulic roller lobes. Three groups of Harold's lobe profiles in all, consisting of a total of 104 lobes. Write down the lobe numbers you want for exhaust and intake, and then give Howards a call.

OH and BTW, don't bother with the Howards Cams catalogue if you want a cam with Harold Brookeshire's lobes, because you won't find them there. it's only on their "Lobe List" PDF file you'll find them.
Here are the three sections of Harold Brookshire's lobe profiles list taken from the Howards Cams website.....

You can also call Jones Cams and speak to Mike about his cams.
