833 behind a stout 440?

I had a '68 Charger R/T 440HP 4-speed.

Before I bought the car, I was told by the previous owner to be sure to have the transmission looked at, 'cuz it leaked bad. The dealer 'checked' it, said it was fine.

I drove it home; about 100 miles. Drove it a good bit after that too, no leaks no problems until the question came up again. Can't recall exactly what brought it back to mind; the car was driving fine.

Turned out the bearing retainer had been broken, welded, and welded poorly with a nice hole at the bottom from which all the fluid could leak out. At the time of the real fix, there wasn't any fluid IN the thing!

100 highway miles home, weeks/months of city driving, NO fluid in the trans. It didn't leak that I observed because the fluid went all gone on the way home!

The end result being nothing bad that could be heard/felt or impacted the trans in any way.

I'd run an 833 behind a 440 and never give it a second thought. They're tough.
