We just had our hands in a 403 olds in a trans am for a friend of mine, We installed a new camshaft, larger valves and did some minor port work. We flat milled the heads to acheive 9.8:1 compression. Added an edelbrock intake and a 750 cfm carb and the guy loves it. Milling the heads reared some intake fitment issues (port alignment) that required milling the intake as well to get everything back inline. It was a budget project and he felt it was worth every penny. His short block is of the stock configuration yet.
