How much horsepower should I expect?

Well as far as the headers go, I did find a link to a pair, but it says it wont fit with the 727 transmission?? It is also a column shift automatic.. Is there a different part number id need? ( What will the HP difference be in these vs. the shorty block huggers? )

I would say they would make 5-10hp more. This is a safe guesstimate from me. The TTI would prolly make more because they are a stepped header. The dougs are only a 1 5/8. Your paying for better clearance and fitting. Same with TTI paying for better fitting and Clearance, but...they are stepped to 1 3/4 and will make a little more power/Tq
