i am going to use a 383 motor+turbo 350,+ just wondering what gear ratio would work good for a 1/2 mile dirt track with 18 degrees banking, talked to some guys that race there + they wouldnt tell a gear ratio, but they all agreed that they use second gear+ do not use drive at all,my car will be in a fun class(beginner class),thank you

depends on your rear end if you are running a gm 10 bolt 7.5 ring rear end i run a 3.08 gear in 2nd gear and about 79-82 in tire ( 205 70 14's)roll you could also go to a 3.23 if you run taller tires like a 75 series or 15 's

I am running a 3500lb. car with a 3.73 gear and an 86 inch roll out tire (255-60-15).When I go in the turn i am turning 6000. I also run in 2nd gear. Hope this helps.
