Adding a 3.09 1st just makes the gear spread terrible. I will drive it more than race it
If you're putting a lot of power to the overdrive 833, I'm thinking you're going to be disappointed with its longevity.
Agreed. Went this route several years back. Actually bent the input shafts twice. Annnnd, I didn't go any faster. Actually went slower. Went back to an 18 spline with 2.65 low and everything is good again.
Also, I don't know if they will chime in, but there are 2 other cars that are pretty impressive. My Son's '69 Dart, street car(Lar414), with a 414 stroker has gone deep into the 11's.
A good friend of mine, OLDIRON has a '67 Barracuda that has gone low 9.90's.
Both cars are very impressive, Just sayin'..........
