Hey all,

I'm strongly considering putting an a500 auto behind the slant in my swinger. The drivers and passenger floorpans were rotted and crappily repaired - the rest of the car is good, so I suspect rubber floor mats. So, I'll be cutting out sheet metal and putting new in; it'd be a good time to rework the trans tunnel & cross member for the larger OD trans.

Engine is a warmed up slant - 9:1, super six, mild port job. With the a500's .69 overdrive ratio, I'm thinking a 3.73 gear would be pretty good - give the slant some extra help in the lower gears, but keep the revs right near 2500 at 80mph (which is pretty regular on the freeways here in Atlanta). I'm thinking 4.11 would be just a little too much. Calculations done w/ a 26.7" tire.

Those of you with OD on your cars, what rear ratios are you running?
