before anyone says anything i know i have to measure which i have never done before cause i've always rebuilt motors with the factory ****. I just want a ball park to compare the pushrod length. stock ls1 bottom end with ls7 lifters pushing off of a tsp228r going to pat. 59cc heads milled by .04'' with a .050'' head gasket. I'm guessing the pushrod length should be about 7.45''. what do guys think and yes i will be rereading the procedure for measuring pushrods. thanks for the help

 

I think you mean 7.350"

 

i added an extra .01'' to accomidate the larger head gasket. but you are right sir. I added the 1 to the wrong decimal place like a retard. yes 7.35 seems right. anyone else care to chime in

 

Maybe closer to 7.300, I thought 7.350 was right for the combo in sig 62cc chambers and I had .130 preload, waiting on the 7.300 for final check.
