<strong>Well hold on.

If you have a part # for your cam Carlitos you should have the base circle info, what is it?

----------

Using those 10 second 346ci cars as a reference does not work. Some are very light and we have little info on the others.

----------

Comp R lifters look for lower preload than stock.

Less preload = noisier valve train but equals more power

Just curious...how does less preload make more power? I think I understand the noisy part. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Less pre load dose not = more power. the 10sec cars I belive you are refering to stock eliminator cars. runs no preload. it's not for more power how ever, It equates too more power but there no direct relation. A lifter that runs with .015 preload is not much better than a lifter that runs with .030 preload. only diffrence is when there pump up say in valve float. The valve will only be .015max open when close. There's no power to be gain from that just safty another safty feature is the locks on the lifter. When the lifter floates if you where to run too litle prelaod say 0 (the reason for that is anothe topic) when the valves float there is no push rod contact at all too hole the lifter together. The only thing there is the little lock. on a stock lifter this lock will not hole the lifter together. The locks on the Comp R lifter is siad too be strong enough to do the job.
The lifter is also claim to pump up slower and pump down faster. This is a purpose build lifter for a paticular group of guys. Is it better than stock yes. s it need for what we are doing...

It' for safty, not for power. it's build to help pull off a very old trick.
is it worth the extar money over stock... Hmmm..
You tell me.

Well, I was primarly referring to the Comp R lifters. One of the senior people at Comp told me that less preload would be more power, and he is the most senior cam designer there.

I'm running the excellent Crane 99893 springs and I can tell you with certainty that Comp makes some nice spring locators, Ti retainers, and bead-groove locks for 8mm LS1 valve. I know this because that's what I'm running. Ferrea valves by the way. Just be sure to clearance the underside of the rockers to clear the wide 1.460 springs.
