There is no casting date on center section?
JA is usually a '73-4 Nova coded 2.73:1, non-posi.

I think the date casting is either an L222 or an I222, either of which translates to a late 1972 production, likely a 1973 JA code 2.73 open rear end for a Nova.

Funny enough, I crawled under my ride, and found my current rear end is JA code, with similar dates. So it amounts to an almost identical rear to what I have, minus the posi and upgraded Currie axles. It's been a while since I built that setup.

I'm gonna pass on it, let somebody else have a crack at it. Steve brings up a good point about power band. I would be probably better off seeking an OD trans in the future to get my cruise rpm's down.

Thanks, all!
