1967 Dart Drivetrain swap.

Yes, apologies, I guess I assumed it was a given to have the bell housing with the trans. It's an A833 out of an A body that had a 360Mag, I'm unsure of the year but does have the standard spline output. And I do have the yoke for it. Found one off ebay.

The motor is coming out of a 77 B300. I haven't taken it out yet but thank you for pointing out the oil pan and pick up, I'll add that to my list.

I do have a V8 radiator in the car already from when I built the /6, I over sized it because it's gets hot here in the south.

As for the wheels, I was actually going to get some wheel adapters for the pattern size if possible and configure them into the width of the rear axle seems how it'd have to be cut any how.

If I'm not mistaken I have to get special headers to fit the A bodies correct?

you'll need a flywheel specific to the 70's era 360, it's different than the magnum.
make sure that the crank on the van motor is drilled for a pilot bearing

you *might* get away with the radiator I/O location on the hoses, but do take note of it. especially the upper might be very close if you're using big diameter clutch fan from the van.

i loathe wheel adapters, so you're on your own there. 100% the axle will have to be narrowed. to me, unless you're getting a smoking deal on that work there's better options out back that provide many, better, positive outcomes: same bolt pattern, weight, serviceability, parts availability. but that's up to you to decide.

exhaust: dougs or TTI fit the best but are also the most expensive. pay less and wrestle a basket of snakes if you roll that way. if you have smog ports you'll need to address that issue by plugging them if the header flange & gasket don't seal that area (however it's good practice to plug them even so).
