Car runs great and has been doing it for 4 years now. it also runs 9.80s with a NO2 shot on it. He shifts it at 6500 rpm with no issues.
There are always better set up. You built what you did it will run fine. What rod did you go with?
I did a long rod 302 years ago I wanted to run EFI Renegade(class rules & weight breaks) but life kids and the house got in the way. So I have this combo that is not the best for the street or track but it is $$$ so what the hell it is what it is run it. I have been 10.30 at over 135mph lifting at the 1000ft mark on the 10.30 run with only a 1.69 60ft. The turbo is to big for the combo and the kit is old and outdated. When it runs well in the 9s this year I will be very happy. Not bad for a set up I was told really was not ideal by a good many people and can drive anywhere I want on the street.
When what you are doing goes against the theory and works just rewrite the theory.
Run this engine and have fun then start saving for the next Dart block beast.
