Just curious what kind of horsepower difference there would be between these two different heads?
All other parts being equal
552 cid flat top pistons trick flow mafia intake 1050 dominator carb running alcohol
The heads are trick flow streets and there cnc 325 heads
I know there are better heads but if a person wanted to upgrade to the cnc heads would the cost outweigh the advantage in hp or would having the streets ported to be the better bang for the buck .
