I put a 4:11 rearend under my slant six and was wondering if I should go to a 3:55? I have upgraded the motor with a cam and dual carbs and such so it is pushing about 200 hp with the original body weight as it is a daily driver.

If you don't do any highway driving you should get along fine with the 4.10.

I drove one on the street with a 3.91 for years, highway and everything. Course, I'm a little more die hard than most I guess.

Why not try the 4.11 and if it doesnt work out I bet you can make a low dollar swap/purchase to get 3.55s.
