You never mentioned the car weight, converter choice & gear ratio. Just my opinion: This info would help us,make a better long term recommendation ,for the engine in the car.
after doing a "bunch" of research, having a manifold flowed before and after my tricks, I wouldn`t spend the extra $ to buy a victor over what you`ve got, unless your hunting every last h.p. you can squeeze out of you engine. a well worked torquer 2 will outflow a stock victor! by the way, I do have a new victor that has the plenum debuggard, if you want one. I don`t have scoop clearance for it w/ an air cleaner-------bob
