For all the parts you have been listing, you are way down on power........

It needs a better carburetor like a holly 950 hp instead of the junk 750 proform street series we have on the motor now!



I doubt your carb is killing you that much...... 750's can easliy run into the nines at your wt........ Have you checked WOT???

It also needs a way better set of headers. The ones that are on there now are only 1 5/8. They are very restrictive!!



Not uncommon to see headers of this size run into the mid to low 11's

The timing needs tuned in. It may be way off because we never got a timing light on it.



This could be completely killing off your power...... Set the timing right........
