First and only pass on my new 408 today!

What stall convertor were you running? We run a 5.9 crate motor in IHRA with a 904. Lupo suggested we step ours down from 5k to 45. We have about 30 runs on it now and the car seems to react a lot better, 60' times picked up .002.

It's a Turbo Action 4200 that was stalling at 6000 behind the 408.
