Firstly I am not sure where to post this,secondly I have Chevy 250 from a 72 Chevelle, I am looking to Get about three hundred horsepower what can I do to see these numbers. I have some headers, offy intake with a quadrajet on it,HEI. What else would I need? Specific parts would be great. I Don't want to much of a fuel eco decrease if possible so I don't want a crazy cam. Would the stock block accept nitrous? I have read that somebody on here makes turbo manifold should that be my route?
