I am doing a 383 myself. The parts, overall, are not expensive. Its a swap that has been done over and over and is tried an true. The LS swap would be reeaaly nice, but fuel injection adds cost and complexity. It may end up being about the same price as a used LS swap, but a carb set-up reduces wiring issue problems. Super Chevy did a 383 build earlier this year and got about 425 hp out of the engine. I already planned to use the same heads they did. The cam may end up being a bit more mild then theirs. I wont be racing it on a strip other than to see what it will do, so all out hp is not my goal. Just a good driving car with a strong engine is all I need/want. I think an old fashioned 383 will fit the bill just fine.
