Will a 1970 440 from an automatic transmission car bolt up to a 4 speed? I;m thinking there might be pilot bearing issues Will the two trans bolt to each other ? No If your asking about putting a NP 833 4 speed into a car with a 440 automatic motor that was never a 4 speed car or had one in it to start with it is doable, but not easy Dang some of them Mopar engineers anyways I did a six cylinder 3 speed car conversion to a 440 with a NP833 O.D. swap last year in a 1966 Dodge Coronet Deluxe two door sedan, I had to add the 4 speed hump which was the major part of that swap as it already had the clutch pedal in it Good luck on yours

I've done it, but it's not easy. You need to cut about 1" off the input shaft of the A-833 transmission (cut right at where the bushing wear mark begins) & use a pilot bearing in the back of the engine.
In my case, the crank was partially drilled.

I used the 53009180 pilot roller bearing shown in the link posted above by CrazyD for the 440 that's in my dad's road runner. It's a '72 block and forged crank w/ an 18 spline 4 speed behind it. Been that way for about 10 years now w/ no issues. Just drive the bearing into the converter hub of the crank.

As it is not a precision operation one could use a hand held drill. A pal tried that & broke a wrist. A safer way is to use a small magnetic drill press. (rent one if needed) Mount the flywheel to the crankshaft & use it as the 'table' for the magnetic drill press base.
