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

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!!

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

Could be a fuel delivery problem...What mechanical pump do you have? What size line? There are so many factors you are listing that could be causing lack of power, the rear gear sounds like the least of your problems. Timing could be way off and slowing you down.

We run a blue generic jegs electric pump and it has very good fuel pressure! It's get's like a steady 7 1/2 pounds and sometimes 8. I forget the size of the fuel line at the moment but it is way bigger then the stock line. How they are ran would have very little if none effect on performance. I think there may be alittle performace difference if we mess with the fuel delivery system but not alot. I think timing is problem going to be a pretty big gain. I Just got a new timing Light and Leak Down Tester For Christmas so will know some answers soon!

Fuel pressure is one thing but flow is more important

The timing light has a nobe on it so I can set it by either adding timing or taking out timing. The timing isn't like real far out it's not like it won't show up on that light or atleast I don't think. If it some how is will just start moving the distributor to it shows up on the light lol. The engine does start up real real easy so it either has way to much or it's way down. All I can remeber if the fuel line is a 6an line.

yes then it goes into a dual feed up to the carburetor

A #6 AN line is 3/8 I.D., those are good for feeding one fuel bowl each The Jeg blue pump is probally a Holley blue clone, made in China It may or may not be suffecient for how fast you want to go A good way to test the fuel system on the car is to jet the carb. up, all four jets together the same amount in size, to see if you can slow the 1/4 MPH down, by making it to rich IF you CAN'T you don't have enough fuel volume (supply), not fuel pressure One of my Carbs. had OEM Holley .110 needles and seats in it, I could not jet the carb. rich enough to slow the car down until I switch the needles and seats to .120 Lots of gremlins out there, some are easy to fix, some are not so easy Some dial back timing lights are not that good when used on a Hi Po race ignition, turn the knob all the way to the left and check the timing at idle, then without touching the knob see if you can figure out what total timing you have above 4000 RPM Let us know your results Maybe we can help you eliminate a gremlin
