D88 Gearing?
Newb Question: What are the trans and differential gear ratios for a 1973 D88? 3-speed automatic, not sure which engine it came with.

Thanks,
PTTM

Depends on the engine. The 350 motor came with a TH350 and 3.08 gears. The 455 came with a TH400 and 2.73 gears standard, though 3.08, 3.23, and 3.42 were optionally available.

rear end
Size of the Engine will also affect WHAT rear end is under the car too. Jim

Thanks. What's the easiest way to figure out what trans and rear end are in the car now?

The easiest way to ID the trans is to crawl under the car and look at it:
