A833 swapping 1970 slant6 dart

[Jack.ezelle]

I have a 1970 dart with a 225 slant with an automatic and I’m looking to do a manual swap eventually, I know very little about the logistics of this, I found an a833 4 speed out of a 1985 d100 for $400 that comes with bell housing flywheel clutch and shifter, seems like a good deal, will the drive shaft need to be a different length? will the transmission mounts be different? Will the shifter be able to fit and will the transmission tunnel be able to fit the new transmission? basically gonna be needed to make this swap work or is it not worth it.

That's gonna be an 833 over drive transmission. You may or may not like how it performs behind a slant 6. Depending on your rear gear ratio, you may find yourself downshifting to third a good bit on hills and inclines.

Thanks for the heads up, that actually sounds good, I’m looking to build it into a semi daily beater type car which would mean the occasional highway so over drive would be nice when needed

It's gonna need some gear. A 3.55 would be the ABSOLUTE lowest numerical gear I'd run and I'd probably go with a 3.91.

The A-833 4-speed transmission from a 1985 D100 is the longer B/C/E-body length and will not fit an A-body without a fair amount of floor/tunnel/crossmember modification. The transmission is about four inches longer than the A-body version. The shifter mount location on the transmission and in the floor tunnel is not the same as an A-body transmission. An A-body or F-body A-833 would be better to use.

You can also swap out the tail housing and main shaft and get where you need to go.
