Thread: Camshaft Selection

yes they like lift and if you never went for a ride in a Z06 400+ hp you should tech they do run dam good on the rocker i would use the stock suff it works very good and Kteck i here used it .if you like the ZO6 stuff i have all the stuff you need ??

Thanks Pat, but AFR supplies the valves, springs, retainers, etc., already assembled with the exception of the rocker arm assemblies. The camshaft and lifters are the only LS6/LS2 items I would need if I go that route.

With the feedback I've gotten about having a little more duration, I may look at that Crane cam and some others that might boost the duration in the 220-235 range.

I was surprised that Comp Cams didn't have some slightly milder cams for these engines. It seems that they go right to .570 lift and higher right of the bat...

I AM NOT SURE BUT WITH THIS MUCH DURATION MEANING 235@ .050 YOU MIGHT HAVE SOME PROBLEMS RUNNING VAC. ACC'S.

I thought about that too Erik, but then if he takes vacuum off the inlet side of the blower, it should be o.k., right?

WHAT I WAS THINKING WAS HOW MANY THINGS DOES HE NEED VACCUM FOR?

With a hydratech brake booster and Vintage Air, I can't think of anything off hand the uses vacuum. While I really don't plan on going near .235 in duration, but it was a suggestion.
