The 72 HP ratings were for "net" HP. Prior to 71 the ratings were for "gross" HP. The net ratings are actually closer to flywheel horse, rather than bare crankshaft horse. I recommend finding a stock 4 bbl carb, and intake, as the 2bbl is going to really restrict the performance with the pistons and cam. If you can't find a stock setup cheap around home, I have one on a vintage 69 motor you could use till you up grade. I won't be needing it for a while, but will want it back when you change over. PM me if you are interested.
