Well.. im going the whole hog on my project and fitting the Grand AM cam from GM Motorsport..

Im thinking 918 springs, titanium retainers.. but what else would be needed.. i know its got a fair bit of lift.. so for valve clearance/so it doesnt hit the piston... whats required? and im guessing i'll need forged internals to handle the higher rpm's too

 

Judging by the specs I've seen it's definitely a high RPM cam, do you think the 918's will be durable enough for any length of time? Ya might think about double springs <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

 

I would definately run double springs on that.

 

We are building an engine for a World Challenge customer as we speak, with that cam 239/251 .570 lift.

we should have dyno numbers next week sometime.

Call me and I will let you know what we did to make it work.

thanks
