I am going to install the duel exhaust/headers and 4bbl manifold and 600 4bbl carb on this up coming weekend the one after. What can i expect for a hp/tq gain fron the headers/exhuast and then the manifold/carb? this is on a stock 74 302 with 8.0:1 comp. Next question, What exactly makes the car faster. I mean i think i understand it. Say all my (238ft/tq) tq comes into play by 2900 rpm, then slowly decreases till 5500 rpm. Now when i add mods, doesn't that broaden the curve and increase it? i.e. after modes it peaks at (for the sake of numbers) 3200 at say 250 ft/lbs and remains above the stock curve to 5500 now. Isn't that the "felt" increase in speed? or what makes 0 to 60 quicker? and where exactly does HP come in? i know tq is a product of HP.... <------ very confused....
