Okay I'm trying to map out my top end rebuild...the last component is the pushrods. I have a 1974 010 sbc. with stock everything pretty much. standard bore, stroke and I believe standard deck height. I am buying a set of IK 180 brodix heads, comp cams thumper cam, comp cams 1.5 die-cast aluminum roller rockers and howard cams retrofit roller lifters. I want to know what length would be right for my setup? I thought stock ones were 7.266" length. comp cams sells a set that are 7.2" and 7.205" that say they will work in my engine setup. If anyone can help or needs more info to help. let me know
