Hi Lads, I have a rattle in my top end of my 351 Cleveland that I am sure is due to incorrect push-rod length. I was hoping someone more experianced than myself could help me confim or correct me on this. I have put in a new cam and lifters and after a 100 miles or so i have a rattle. The push-rod length I have is 8.425' I have non adjustable yella terra roller rockers and a hydraulic camshaft with specs of 224\234 [email protected] thou with 0.536int. 0.562exh. lift. it has new lifters and was run in correctly. I originally thought that it was from to shorter push-rod, but from what i have been reading, they seem to long. Any input would be greatly appreciated.
