Question on springs Will 918's work with this cam 232/234, .595"/.598" or would it require duals? I was reading the Texas Speed site and it rates the springs at .600 lift here is the quote
TSP Camshaft, 918 Springs & Pushrod Package
Item#:
CamPkg-1
Your Choice of Camshaft, Comp Cams 918 Springs, and Hardened Chromoly Pushrods
With This Package You Get:
Any Camshaft You Want!
Comp Cams 918 Spring Kit (rated to .600 lift)
but in another section if you get them separate you get a section on the preface that says .600 also but when you open it you get this rating
"Beehive Shape Ovate Wire Springs
The 26915 and 26918 Valve Springs are specifically designed for the LS1 Chevrolet cylinder head and can be used as stock replacements or in performance applications all the way up to 0.625” lift and at engine speeds to 7500 RPM."
Okay so whats the deal?

how high you plan on spinning the motor.... if only to 6500 every now and then the 918's will work fine. and less weight then duals.
Duals for over .600 lift and 6600+rpm IMO. I have seen 918's last to .625 lift before... but that is playing with valve float potential. IMO

Okay so 918 will/should be good for a 595/598 lift. Its a A4 so it goes to redline on its own and that is only at the track, every so often. But I still wonder why they rate it at 625 in one section and 600 on another. I wonder wihich one is true.
