I'm building a 383 also ,for the pure stock drags,( building a 67 gts-gotta use the 516's heads) and was just wondering what I could hope to achieve with a .30 over stock motor.
Thanks
Whats their definition of "stock"? Blueprinting only? any headwork allowed? If truely totally stock, with some tweaking and really good machine work, my guess would be around 350 Hp. This assumes you have to use the stock intake, 516 heads, bone stock cam and exhaust. I would think it would be pretty hard to make any major power improvements while truly staying "stock". Sounds like a difficult class!
