1970 Dodge Dart 318 upgrades

There is probably no way to do this on the cheap, it isn't like there are small block Mopars with 4 barrel setups sitting in the u pull yard, not in my area anyway. But lets say there is for sake of fantasizing, the OP takes their two barrel 318, slaps a Carter AVS on it, will he/she any improvement? If the car runs like crap now, or performance is off with the two barrel, figure out why, is the crappy nylon timing gear still on the car? could be. I had a 69 318 that really woke up after that junk timing set was replaced. Best money spent would be tune up the two barrel or at least figure out if it is mechanically sound and fit for a tune up. get it running good with a two barrel, and go from there, a two barrel car should be able to lay rubber and do 120 mph use that as a seat of the pants test. basic testing and tuning is on the cheap.
