Re: About how much horsepower should this setup have?
you should gain about 60-80hp to the original amount. I believe that those 5.7' had about 210hp so you have about 270-290hp. However, you will loose low-end power but you should notice a good amount of power in the 4000-6000 rpm range.

If you don't mind me asking ( camaro305sb ) what's wrong with my answer. My dad had a 88 formula 350 and that car had 220hp from the factory and its the same 5.7tpi i would think.
