What gears for new MWC Fab 9?
 

Car is a street only car. I was thinking 3.50's. Mileage and quiet is a plus. I figure I'll have enough power to be happy.

Car has:
427ci ls1. 550-600hp at the wheels
flt lvl 7 4l60e with 3400rpm yank verter

350's are cool but i would go with 373 with an auto..

I have 3.73s in my car, interstate isn't bad with a 26in tire and the auto tranny 4l60e..

If you plan on going to the strip and having sticky tires/wanting the faster 1/4 time then I'd say 3.73's or any racing at all.

If you are then going to cruise more, spend more time on the highway, then maybe go 3.50 or so.

Its all up to you and I think with that power your not going to be disapointed either way.

I'm going to spend most of the time cruising. Do I want to go smaller than 3.50's to something stock-like? 3.23's for example?

I say stay with the 3.50's you do have overdrive, so take advantage of the better gear.
