I am real curious to see how it runs as I would NOT have built/ordered the motor as he did. I think its going to be slower than he thinks.

My 555 13:1 alcohol motor with first two second of run at -19 degrees has 335cc Dart Pro 1 heads, car weights 3350 and I am 200lbs runs 9.03@153MPH. 2 inch headers. Car still have power everything, stereo, carpets, just a race seat is only internal change other than safety stuff.

I am really curious to see how this motor runs with that big of runners/headers. I think its going to be slower than mine. If he cranks off a 8.6-8.7 I will be impressed. Anything less its a disappointment.

I only look at real world results on the track to determine good, better, or best.



I would like to know what this motor runs, I ran a set of BMF 385 heads on a 565 alky injected motor and that think would fly but it was in a 2400 pound car.


I agree that should have. This combo I'm afraid is not going to be as good. There other big thing is it is pump gas 10.5:1. Still it should do everything mine does with the extra inches. Dyno was 936 at 6800. Again I believe dynos like Democrats.. Lots of big numbers and no results.
