Ok, here is my question. I have a 1984 Olds cutlass supreme 2 dr with a 307 stock. I want to replace the engine to a more powerfull one. I live in Arizona and the emission laws are an issue. What should I go with a olds 350 or a chevy 350 and should I use the exsiting carb and emmission equipment with the 350? Will it even be compatible? What would be benificial in the long run...oh also definetely want to keep the a/c! thx in advance.
