I just wanted to thank everyone for their help. I got myself a TDC tool and found that the balancer had slipped or the timing mark on the front cover was wrong, but either way the mark was off by about 2 inches. I got the valves adjusted using the TDC method and re-timed the distributor and now if runs like a champ! Still a little rich, but I think the carb is jetted way too big. One day I'll get the carb jetted down and get the racey camshaft out of there along with some new pushrods (they look like they were a mix-n-match of leftover parts) but that's going to have to wait until I steal this engine out of my wifes El Camino and put it in my Chevelle!
