i just bought a 1952 m37, the motor needs rebuilt, im looking to put a v8 in to it!, the flat 6 thats in it has everything, not sure what to sell it for any ideas? plus im stuck on what motor i should put in to it. does any one know if they make a chevy bell house for the np420? or should i go a diffrent rout ?

I put a Dodge 318 Poly into my Power Wagon, made a huge difference. I know a lot of folks have done the same with M37s. My suggestion is to keep it a Dodge engine, not a Chevy.

...sigh...

What is your intended USE for the truck?
What is your budget?
What mechanical capabilities do you have?

Lots of discussion on this over the years - any engine swap depends on what your ultimate plans are for the truck.

Many engines - from 353 Detroits, to Cummins 4B diesel variants, to the excellent Small-Block Chevrolet motor, to Ford & lead-anchor
Dodge motors have been installed in the M37. LOTS of info as well in the forums... as well as info available on the Power Wagon forums -

See the comments on the other forums that begin to discuss what engine options are available, then disintegrate into a peeing match over
'Dodge is better than Ford is better than Chevrolet' - some powertrains swap in easier, and kudos to the people that love one brand over another.

The truck doesn't know what powerplant is under the hood -

Consider also that other systems - brakes/steering/cooling - will need to be brought up to snuff, regardless of the engine of choice. Note that the
NP200 transfer case & standard 5.83 diff gears don't like to be hurried down the road.

Various transmissions have been installed behind these as well...

And don't DARE put GM brakes on your Dodge, right?
