Just tossin arround some ideas on how to squeeze every bit of power out of this thing while remaining with iron heads(port/polish/valves ect) -781 casting.
Costwise its about the same for a new intake/carb setup as it is to grab a dual quad.
But which one will perform better?
If there are power losses with one, how much could i expect to lose.
Several magazine dyno tests have shown that a good single carb usually makes more power than multiples, regardless of engine type or cubes. But the WOW factor of multiples is worth 20 hp any day of the week.... amen.
Ole Shelby said that there was NO difference in power on the 500 cars. That they all were within 5 hp. Dyno testing then and recently has proven him correct.
