Have not been on here in a while but here goes my opinion. Quick Fuel and billet carbs are over rated... They look great. I recieved my carb back from them... they installed new metering blocks, changed my front power valve, new gaskets, and cleaned it. They fixed the secondary pump shot so it was not shooting up through the IAB. I installed it tried a bunch of different size squirtrs, jets, was all over it for a couple days and the thing still sounded just like a delay box/rev limiter when you would floor it ffrom a stand still.....da, da,da,da,da,da,da,da,da,...3/4 throttle was ok...only when you floored it.
I ordered a new distributor/ billet pertronix,and changed to my third coil thinking that was it... I was checking voltage to the coil etc....finally I got a 750 Vacuum secondary off Ebay for $81.00
Put the carb on and tuned the A/F at wide open.... no more stutter, took it to the track and ran an 11.75 at 113. (on NOS) car was miss firing pretty good and didn't want to rev past 5000 on the spray and realized after I got home that my plugs are gaped a little to much... so I shrunk that down to .025 and am going to try it again maybe this wekend.. the car feels like it will run high 10's... I ran a 7.30 1/8 mile pass on the last try at 93 mph... but it was breaking up so bad I got out of it so I wouldn't hurt anything...
LONG STORY SHORT: Quick fuel annular race 750 for sale!! My $81.00 straight booster ebay special responds awesome and runs perfect... I spent over a year with that quick fuel crap
