I would think you could be in the 6 to 650 range with sticks and a dual fueler

:D Someday........... I am just happy it runs good now, after all the issues with injectors and lines.

Very nice run. As stated there is more in it. I hit 502/988 on stock trubo and stock tranny. My trans hates me now lol

Thanks!!! I sent Jeff my logs, he is going to make some changes. It runs so good, but would like to see what it is capable of the way it is, I'd like to do maybe 30 or 45 over tips and a modded pump or another pump, but I have a feeling it wouldn't last long?


If I went 12.65 with a dyno reading of 494/956, and now I am roughly 523/1084, how much faster can I expect to be?
