I agree it sounds crazy. Thank god for the dyno as the plan was to run the quadrajet! The even crazier thing is I am making 490hp 577 tq with no trick or fancy stuff. No porting, no trick anything. I haven't even rejetted the carb, or adjusted the pump shots. Idle is 750, very stocking, vacume 15 inches. 35 degrees of timing. Stock hei. It seems like it took a year of reading to sort the bs from what works. Mail order, assemble. Toss the aftermarket intakes, distributors, porting of heads, ect.
