I am doing a cam mod on an LS1 in my z28. Its a Comp Cams kit thats comes with cam, lifters, springs and double roller chain and gears. 522-529 lift 212-218 duration. if you need more info on the cam look at summit.com part# cca-k54-412-11. my question is, what lengh pushrod do i need to go with? info i have says stock is 7.318" but the closest i can get to is 7.3" but i see a lot of threads talkin bout 7.4". please help as this is the last past i need to get started. i will be porting the heads and for now will be useing stock rockers.

You need to buy a pushrod checker from Comp ($20)
