Quick91LX, I've got the stock 2:72 rear end. With the 3:27 gears, it will give me just under a 20% increase but keep the gas mileage in check, the 3:55 gears will give me just over 30% increase but hit the gas mileage a lot harder. I'm looking for just a little increase in "snap".
Mike, thanks for the info on the Lincolns, there's a /95 Continental and an /88 Town Car that I could check out in the next week. I can get the entire diff for just under a $100.00.

I have 3:27 gears, I put in a complete housing from a 94 gt in my car. I have been satisfied, good driveability and nice MPG
