someone gave me the engine. this is what i know about it. its a 305 bored to 350 or at least close to 350. it has a proformance camshaft and a 600cfm holley carb. knowing that i can assume that since he had to get new pistons anyways he probably got high compression pistons. i know holley pumps are rated badly but i figured since i have a holly carb that they would probably work the best together.
