Engine ran great out of 74 dart parts car. No smoke, didnt knock, decent oil pressure. I was gonna change seals, gaskets, core plugs, water pump, clean out and reinstall the oil pan. Add 340 exh manifolds, and a nice aluminum intake with a 600 carb, electronic ignition w GM HEI.
If you are not going to do head work or swap cams, then a lot of intakes would do you great service. Here is a short list of easy to find and easy on the wallet, but there are others as well:
Factory Cast 4 bbl
Old Holley Street Dominator (I just bought one for 30 bucks). I'm talking the one without the divider in the plenum
Edelbrock performer
Weiand Action Plus
I would suggest putting new valve seals in as well. Those LA small blocks are great for having them get brittle. Then you smoke when you start up, or idle for a while at a stop light. Also, all those brittle, broken valve seals end up in your oil pickup screen.
