Tony,
This cam is so mild iit should be illegal to install it in a Corvette. My Crane Energizer has 216 @ .050" lift both intake and exhaust and tops out at .454" lift on both sides. Not the latest tech but not bad for $70. Works real well with the headers and Performer manifold.
Don't give up anything below 2000 rpm but above it it really pulls. Little lope at idle but not bad. Also pulls down 18-20 mpg on the highway. :cool:

Yeah I'm not sure what all the numbers mean but when
you compare it to the others you can see how mild it is.
Thanks Steve I'll keep the Crane on my list. I can't wait.

Recommend Comp Cams XE262. Very popular on the forum with the small blocks. Will require upgrade over stock springs. Their website http://www.competitioncams.com has lots of info. Worth checking out before you decide.

Have rec. many times- Comp Cams XE262 or CS268 if you drive hard for 4spd. !
Comp Cams CS268HE or Crane version mentioned above will work w/ stock valve springs. Comp Cams XE262 is similar, needs matching springs.

Re: (45ACP)
Does anyone know how to read the website chart listed above? I'm used to duration at .050". The chart looks different then the cam specs listed by Comp cams or crane? And I'm a newbie with cams anyway.

Re: (TTop Tony)
Here's a little chart I put together to help me decided on which cam I wanted to buy.
0.050" 0.050"
Lift Duration
Comp Cams 260H .440/.440 212/212
Comp Cams XE256 .447/.454 212/218
Stock L82 .450/.460 222/222
Comp Cams 268H .454/.454 218/218
Comp Cams XE262H .462/.469 218/224
Comp Cams XE268H .477/.480 224/230
If I was you, I'd at least go with a L82 or better cam - say a 268H.

Well it does not like the use of tabs or spaces so the columns are Cam ID, 0.050" Lift, and 0.050" Duration..

Ganey,
You don't think the XE262 is too much for my stock bottom end? Thats really my only concern with it.

The Comp Cams are 110 LS & stock L-82 is 114.
