rear end nightmare! NEED HELP

20 dollars sounds good. im useing the stock posi carrier with the 3.42s out of the series 3 and a spacer. email me at regalman4925@yahoo.com

 

Whoa! I was thinking about changing rearends or the gears in my rearend, but after reading it seems too complicated. I have an '86 Regal Limited w/ 307 crate motor, 5A heads, A5 intake (I think), Edelbrock 650cfm (#1400), True Duals (no cats), Turbo 350 Trans rebuilt last year when the 307 crate motor was put in. Over the past year since engine and trans install I have NEW....radiator, starter, battery(optima 1000 amp), water pump, fuel pump, gas tank & sending unit, A/C compressor & accumulator, +15" Buick Rally's. I don't want horrible gas mileage, I get about 15mpg street/ 17hwy. I won't be racing this car because I feel the engine isn't made for it and I don't wanna be embarrassed. But I do wanna have a good Street rod.....I like burnouts and donuts! Not much more than that is expected from me. What do you guys suggest as far as a rearend goes for my setup (if u can call it that)? I was thinking that I wouldn't lose too much on gas mileage if I went to 3.42 rearend w/ an overdrive 200R4 trans swap. Since reading this thread maybe 3.08 is better? Still kinda clueless.
