You guys DO know ,you're going to have to put a custom 12 bolt in that car, in order to be able to play with the gears?
I'd figure out a baseline on the ratio, and then ,when you go lower and don't pick up 60' but lose MPH, go back to where you were!
BTW, if you're not too deep into that car, I'd back right out of it ,and into a 78 Camaro 305 2 GC 2bbl car .
You could use the 8.5 rear that comes in them.

If you're looking to build a "dime rocket" then I would absolutely agree with Mark. There's no cheap way to put a rear in a Monte Carlo that will give you any gear selections. I think that both combos have about the same overall potential.
The only other thing to consider (other than having a car vs. finding and buying a car) would be the difference in weight between the two. The Monte Carlo has to weigh only 3170 to make U/SA while the Camaro has to weigh 3770. I like towing light cars.
