Gear ratio for rear with GM Vortec Engine
I'm looking at 97 Thunderbird or Mark VIII irs for my '37 Buick.
1) Can anyone recommend the Best 97 Thunderbird rear gear ratio with GM Vortec LH6 or LC9 and a 5 or 6 speed automatic transmission? I want the car to be a daily driver so probably the best gas mileage that still feels like the car is not underpowered. The combination will be in a '37 Buick Roadmaster with an overall weight of 3700 to 3800 lbs.
2) Is positraction important?
3) Is alum of the Mark VIII worthwhile? How much does it save in weight?
4) Can I tell what a rear en is by looking at it?

I wore a camouflage T-shirt once. The response in the pub was "Oooh, it's a floating head!" .
