Thread: Chevrolet performance 350 crate motor

Tweet

So i am planning on buying a Chevrolet Performance 350 C.I.D. 290 HP Engine Assemblies 12499529 from summit racing. I am putting this into my 1993 gmc k1500, and i plan on putting a new y pipe in the exhaust and taking out the cat converter (shhhh) but im not sure what to do with the fuel. Chevrolet performance says that they came up with that 290hp using a holly 670cfm tbi. I have heard to never use the holly tbis because they are unreliable and overpriced.... i also saw that you can put a 18psi spring in the throttle body and upgrade the fuel pump..... im not really sure what to do. Ive never done much with car engines, i can do stock repairs and such but i dont have any experiance in modifactions. What can i do to get that 290hp or close?
