[68 P.O.S.]

I agree with Mike C, always timing first. You have to have your base right before you do anything to the engine. You're timing is too retarded. I've had the same thing happen before and bumping up the timing fixed it. Set your initial timing to 12 or 14 advanced and you'll see a much different engine. I also agree on upgrading to a HEI, but not a Skip White. I followed the hype and picked one up and it was dead on arrival. There's a reason its so cheap. You'd be better off finding one in a junkyard or spending a little money for something much better.
