I just finished the build so I can't speak to valve spring life yet. As for rpm I was planning to rev out to 6800 rpm max. Valve spring life was my greatest concern though so hopefully I won't regret going with the psi 1511ML.

Should be fine just remember what I said about the DOWN SHIFT.

Lots of good info Kip. I would like your opinion on these following lobes, the number is the diff between .006 & .050

1) LSK 50* (not recommended for street use)
2) XER 49* (I got tired of the noise)
3) LSL 50* (My customer has a 227/243 in his 2010 Camaro, and is very quiet)
4) LXL 52* (advertised as being quiet, and heard only good reviews)

If I was going to put one of these in my engine I would use the one with 52 degrees. Now how long is the ramp from the base circle to .006? this can also make some noise. But if have run the LSL then I am sure it is good.

Kip Fabre

HARD or SOFT lobes? this a true story. We have a customer that races in a class that can only use a GM create engine no changes stock engine and stock cam specs HYD GM cam. This is for circle track car. The stock spec are if I remember correctly are about 200/315 in 215/300 ex-112 so we made some lobes with the same duration and lobe lift but softer he called back and said it made 100 more Hp at 7000 yea right. It really did at 7000 the stock cam floated the valves so bad it fell off 100 hp the one we made went up to over 7300 so now he changed the rear gear in the car and has the advantage.

Welcome to the board Kip. Someone of your knowledge is an asset here. The shop that I started in, Herrick's in Simpsonville, KY, was a customer of yours in the 80's. Your experience in cams is well proven.

Russ K,
What lifters are you using? Have you used the same lifter with the cam swap? Bought exact same NEW lifter? I've read the BTR has had success with his SLR lifters and it might be worth trying if the noise bothers you enough giving you cam is SUPPOSE to be a quiet design. FWIW.

KIP Fabre,
You mentioned old CM cams and new CM cams. Are you new to Cam Motion or a long time employee?

thanks,
Jim

Reused the stock replacement Sealed Power lifters. Asked Brian about the SLR lifters. They are only for a lifter tick @ idle when very high valve spring loads are used. He said they are not needed with the Platinum springs.

Thanks for the welcome Jim was a great guy he was one of my first good customers.

Kip Fabre

I must have said something about the way we made cams in the early days compared to now. I am not new to CM I have been there starting in 1978.

Kip, I have a question about proprietary cam lobes. I know of one person who has proprietary lobes through comp cams and am curious if any person/company has proprietary lobes through Cam Motion? Also, does the individual/company create the lobe design, or does the cam manufacturer/grinder do this, or is it a collaboration of both parties. I have always wanted to know this.

Allan at futral designed his own lobes as well as Geoff with his EPS series both are ground on a cam motion core . I know Geoff deigned his own lobes just as he did when he worked for thunder racing. Allan to the best of my knowledge developed his independently also. Cam motion just cuts the cams oon their cores

That's what I was thinking, but wasn't 100% sure. You would have to be extremely knowledgable in order to design your own cam lobes.

Kip Fabre

Most of the customers tell us what they want and we make the lobe that way. They will say I want a lobe with X @.006 X @.05 X @.200 with a X lift lobe sometimes it is impossible to give them what they want but we can get close. Or if they want something I know will not work good I will just say I will not make that. Sometimes we use our lobes on there cams and put there name on them.

In the cases a said person or company has proprietary lobes, the general public would not be able to use them, unless ordering through that said person or company, correct?

Kip Fabre

That is correct we have had people try that before. If you have a company you like you can order a cam through them and use our lobes but we will not sell there lobes.

Most of this stuff is over my head but I enjoy reading it anyway. I haven't seen a thread on tech like this in a really long time. Reminds me of something Tony Mamo did several years ago.

Thanks Kip!
