A833 OD to early big block?

[tysoncode11]

Hey. So I’ve been trying to search around and see if this is possible. My truck is a ‘81 chassis originally a slant 6 with the a833 overdrive transmission. I bought an early model 383 for the truck. What do I need to bolt the transmission to the motor? I have a regular 4speed a833 big block bell housing lying around. From what I’ve found, it can work but the bell housing either needs to be machined larger or the input shaft on the a833 od needs to be machined down. Is that true? Also what is the best way to tighten up sloppy gears without fully rebuilding the tranny.

Can check me out on YouTube!

Where are you in Saskatchewan?

The bellhousing will need to be bored out, the input shaft bearing is bigger on the overdrive unit than the standard 4-speed.
