i'm rebuilding my motor and trying to figure out what size pushrod to use i have ls1 heads ported and mill .035 and a comp 230/230 591,591 cam, should i go with the 7.35, or the 7.4 lentgh, also dont you need adjustable rockers to go with a shorter pushrod if so then i cant go shorter because i have the yella terra rocker 1.7 ratio i'm gonna use and they are not adjustable

 

Err...if they're shaved then run the 7.35. Could always call comp and ask them too

 

i've been told by a few shop techs that they use 7.4's and shim the rockers. if i already had 7.4's, i'd just shim em'.
