Its a Thumper 1250 carb and its on pump gas 93 with E10, so that requires an AFR of around 12.2....Friday nights pass showed it was close to 13.8 in high gear. Saturday I went up from #104 to #106, and it looks like its around 12.5-12.8 now. I still had jets in my hand when they called us to the lanes....But it was much better, and I gained almost 2mph in the 1/8th.....So it probably just needs to go 1-2 more. I will order them, but I doubt I will run this car again this year. My belts are out and I was lucky they let me run actually let alone, I made it down to the last four cars....Not too bad for a street car. Going to have to figure out what kind of tire to put on it for next year. Thinking of trying a 315DR in R2 compound....Its shorter and will kick the rpm a little.

And yes Hi-Po big valve heads still....I could tell it wasn't pulling real good yet, so the jetting needed to be better before pulling it that high, and my 20 year old 7k rev limiter chip was hitting at 6600....
