Morning. i'm getting ready to grab some breakfast and spend the day on the car.
I may not be that much help afterall. I've never heard of a 383 in a sprint before, and although I know carbs excellent, my sprint experience is with a set of hillborns. I'll tell you what the gears are if you'll tell me the numbers that are stamped on them (I'm heading out in about a half hour (7:30am))
1/5th mile...perfect below is our 1/5 mile track, from the pit crew stands, last summer.
