Alright guys, the deal is im building a LQ4 and I have some ls6 243 heads with a .614 lift cam, and some harland Sharp rockers, so my question for you guys is as far as pushrods, do you think ill be good with stock length (7.400) pushrods? and should I upgrade to hardened pushrods, or is it safe to use stockers?

 

Teh Intarwebz measured your engine and says you need 7.41913" pushrods.

 

Nobody on here knows...period. every engine is different. Measure for length to be sure. If anyone tries to give you a direct answer, don't trust it.

 

Did you set rocker geometry first? If not, measuring for pushrods will provide the wrong answer. You need to set the rocker wipe pattern then measure for pushrods. Also, hardened pushrods don't buy stiffness. That can only be done with diameter.
