I bought a 79 C-10 a few weks ago, and recently discovered a rod knock. I'm going to pick up a 86 suburban from a friend and rob the drivetrain from it, 350/700R4 3:73 rear. And I would like to put a cam in while i'm doing the swap, nothing real big. I was thinking about one of the comp thumpr cams, but another friend said I should go with a lunati voodoo cam instead. I am wanting it to sound mean. Any suggestions?
