biggrin Holleys

Would it be worth putting a 350 Holley on my 250 pre cross flow? The engine is stock apart from a shaved head, extractors and a 2 1/4 inch exhaust. How much extra power would i get from this if i were to do it?

Re: Holleys

imho i wouldnt go near a holley. alot of ppl will disagree but i reckon they are an over-rated peice of rubbish. they are good for a straight line but no good round corners.

speco make an adaptor plate to run a twin barrel weber on a single barrel stromberg manifold and thats they way i'd go - just an opinion
