I need help figurin this thing out, I've gotta 93 lx with a 5.0 n it. I went from a stock roller cam to a f303 roller cam. I've got it running but u can hear a sound from the per end that sounds like it out a oil but I've got 40psi oil pressure. The rockers are torked to 20 pounds and u can't really hear the ruff idle it should have. Does any one have any suggesting on what the issue might be??
