I have 350 out of a 73 caprice and wanted to know what would be the best route to get 350-420 horse's out of the motor? It has a poorformance cam in already, but the block was rated at 140 horse's. I got headers, holley 670 carb., edelbrock rpm intake, holley hi pro. fuel pump, hei dist vac. advance on it already. I bought the motor from a guy that flat out lied about what it could do. Looking to maybe spend another grand in it, if it helps it's in a 86 caprice with a 700r4, with stock rearend.
