stock block :headbang: I believe there shooting for 25-28psi
Highest pull of the night was at 20 psi. With extensive tuning, we squeaked out 653. Unfortunately, I need to buy a new fuel pump. Last fall I could get low 11 a/f ratios for an entire 1/4 mile pass at 25 psi. Tonight we couldn’t even maintain 12:1 at 20 psi. Fuel pressure tapered off quick when we tried to run 24 psi. I guess that’s what I get for messing around with an Aeromotive pump when I know I should be running a Weldon.
Anway, here are the details-
2nd gear pull with 2.93 gears and 28" M/T ET Drags.
110 Octane leaded race gas.
HP peaked at 6600 RPMs with a 12.4:1 a/f.
