My mistake. I thought you had a Quick Fuel 950 that has a larger venturi than the Holley 950. People rip on the 950HP for having a 750 body but they always seem to get it done on a wide range of combinations.
There's probably more left in that with further tuning 1050 though. That it matched the smaller carb to 60' is encouraging.

Yes I agree...I believe its the stock 950hp metering blocks holding it back.On the street the 1050 felt sluggish..the track confirmed it....On a positive note even with the car running slow for 2 runs it was still 11.34/11.36 at 120...
