Another Cam question...

I was originally going to order the cc503 cam... but i contacted COMP Cams and they recommended their part number 07-467-8 ... i have a 350 bored .040 over with edelbrock 60859 heads, TES Headers, 1.6rr, and HSR. the problem i see is for my heads the max valve lift is .575, and the 07-467-8 cam with the 1.6rr will make it .576... will this be a problem? ill post cam specs below... thanks guys

cc503:224 int./230 exh. @050 0.503 int./0.510 exh.(1.5) lift 112LSA 1,800-5,800rpm

07-467-8: 230 int./236 exh. @050 0.576 int./0.570 exh.(1.6) lift 113LSA 2,000-6,000

I don't think .001 extra will be a problem
I assume you mean the max is what the springs are rated for.If you want to run higher lift need to change the springs

Re: Another Cam question...

bear in mind that the hydraulic part of the lifters will eat about .004" of your advertised lift, so your actual valve lift will be more like .572" anyway. And that is with 1.6:1 rockers, I do believe.
