measuring for pushrods on my 427sbc and had a few questions . Do most use same length on intake and exhaust ? Most lobe lifts are diff for intake and exhaust so it would make sense to have diff lengths correct ? Or am I wrong ? Just can’t seem to wrap my head around this For instance my gross lobe lift is around 600 on intake and 580ish on exh . For my custom Straub camshaft What do others think ? .
