Post subject:  New member needs tranny and rear end info

Just joined and havin' a a pain gettin' around in here! Anyway, just bought a '66 /6 Barracuda automatic on the floor. Supper 225, fresh rebuild, bored .040 over so now
a 230. 3 speed torqueflite trans. Is this a 904 like the ones that came in the same car w/manual 3 speed? What gearing does the rear end have. This car is stock original.
Just turned 80,000 miles today.
I can get a stock rear end from a '66 non-fs Cuda but the guy doesn't know what the gearing is. What rear end (s) would have come stock in a '66 non-fs 273? Looking to upgrade to an 8+3/4 rear end. Thanks.

Sorry for the "pain"...this message board is running on two servers anhd one is down at the moment, that makes things slow to load.

Anyway, the rearend your friend has is most likly a 7 1/4, like the one already in your car. most 7 1/4 have the gear ratio stamped on the housing so have him scrape off the grease to find the ratio.
