RE: Help! Keep wiping cams!
By cuzncletus - 06/10/2004 8:35:40 AM; IP 68.220.43.49
The engine has stock Edelbrock springs. I've changed cams four times including one hydraulic that had within .010 lift with no problems. Lifters were new. Edelbrock says these springs will go past .600 lift with no problems.
The first time I built this motor I put it together myself. Now it is in a shop being built by a long-time Ford mechanic and racer. The cams wiped during the 20 minute break-in. While I haven't watched the asembly, he's built dozens of motors I know of personally with no problems. I'm giving this background because I think we can eleminate the basics.
The first cam to wipe was "broken in" by the manufacturer on a machine where the cam is run in for a period of time under reduced spring pressure. I thought there might have been a mix-up on lifter to lobes during assembly and that was my assessment of the initial loss of the cam; simple assembly error, though the builder swore otherwise. I wanted the second broken in the old fashioned way I'd always done it; fire it and run it over 2000 for 20 minutes. Result? Even more destruction.
Question to Gerry Proctor or others with knowledge and experience with FE's: Could the restriction of oil to the rocker arms (rollers) cause a lack of oil pouring back through the valley and onto the cam? Is this a significant factor in oiling cams? I know restrictors are used routinely in the assembly of FE's. Right now, my mind and the builder's mind are just thrashing about for answers.
This thread, so far...
