Quote: How do I figure out what length pushrod I need? is there a measurement procedure?
Yes. It usually involves buying an adjustable pushrod made for that purpose (buying two makes it easier). Most cam manufacturers sell them. They come in various lengths and end configurations.
Good deal...I will see if I can get some. I will have to research the procedure to determine proper length. Hopefully it will be a fairly simple process
Yes I did pump the lifters and pre lube them. The heads are 340 specific heads and not magnum heads. Speedpro forged pistons with valve reliefs (2). I don't think there any valve piston issue. The noise seemed to be coming directly from the rocker area. It became pronounced when I removed the oil filler cap. I suspect the pushrod length is incorrect. Thankfully I didn't find any metal in the motor.
