I don't know what the numbers were, but in the 80s I had a .030 over 318, basic rebuild as far as I know, that I stuck a set of 340J heads and matching factory 4 bbl intake on, using a tq and stock exhaust manifolds, no idea what the cam specs were, but that little motor in my rusty old 70 Dart GT sure embarrassed a lot of people. Granted that the 80s generally sucked in performance cars, but it was pretty respectable for the few $$$ I had invested.
