Thread: SBC 350 pushrod length

Tweet

If you need shorter pushrods----stack up of tolerances from new seats maybe not being installed deep enough, valves to seat not being proper depth, and the crane rockers not the exact configuration could cause you to have a significant differance in geometry. did you check the valve stem height against specs??

No, I leave that to the machine shop. It's a reputable shop though. The engine runs fine. I broke in the cam per intructions, Has great power with no valve train noise. I wanted to check the pushrod length for good measure because I had a little valve train noise with the other cam. There are shorter pushrods for purchase, just not the length my test is showing I need. Maybe I will do a couple different valves to make sure it is all of them and not just the one.
