Hi! Does anyone know how much hp is in a all original 1973 Mercury Comet GT. I have a 4-barrel Holley Carb, Edelbrock Air filter, dual exhaust on a 302 v8? -Thanks-
If it is all original, it wouldn't have a 4-barrel holley carb on it, or dual exhaust. So, based on old researched numbers, the stock (all original) 73 302 has 138 hp. Not much, but your new intake and 4-bbl carb will help, as will the dual exhaust. I would gues 150 hp.
