I replaced the 318 in my 90 van with a 360.I put a mild cam in it and I noticed the smaller base circle of the new cam.I checked it and found it was .020" smaller than the stock cam.When I reassembled the rocker shafts I looked to see if the pushrods were preloading the cam and I thought once oil pressure was there everything would be ok.I was wrong.Now the rockerarms are a little noisy from the lack of preload and I need longer pushrods. I know there is ways to check this but for now I just want to find a pushrod that is a little longer than my stock ones. .010 should do it. Any ideas?Maybe pushrod's out of something else?
