Found a clean 69 Coronet 4-door that had a 318, 3-speed column shift. The 318 is seized up, but I have a fresh 383 on the stand. Can I keep the column shift with the 383? Will the 318 linkage rods clear? I just think it'd be cool to run a 4-door with a 383 and the three-on-the-tree.

No actual exp with that setup but I'd be surprised if it wasn't doable. I'm sure there were bb/3 speed on the col B bodies. As you know you'd need the correct bell/related pieces. Holler how it turns out & here's a BTT for ya & maybe someone will further clarify

I don't see any reason why it couldn't be done. But I would prepare for plenty of backyard fabrication.

As long as there's a bellhousing that fits the 3 speed and will bolt to the B eng, it should fly. I recall that my 68 318 coronet had the 3 speed with larger output spline too(727-833) size.

I have the bellhousing with the dual bolt patterns. The trans will be in the same position in relation to the column levers, therefore the linkage rods should fit. The only real difference in the bellhousing is the bolt circle where it bolts to the block. Starter location is not an issue. The only real wild-card is will everything work with the headers? I'm willing to modify a primary tube to make it work. The 383 is basically stock, so it push comes to shove, I'll go back to cast manifolds. It's not a race car, it'll be a daily driver.

There were plenty of 361 B block trucks with 3on the tree. Check into them. It couldn't hurt.

I think that's a cool swap.

I almost bought a 69 Polara 500 convertible a couple years ago that was a factory 383 2-bbl three-on-the-tree, so there is a bellhousing available and I am sure you could get the bellcrank and other linkage parts to work.
