My grandson has a 78 Dodge 4x4 truck that is really rough. It has an LA 318 that froze and broke the block (we won't get into that).
Someone gave him a 360 that has had the intake off of it for a long time, and the cam and cam bearings don't look very good. The wore out, and scratched up cam bearings are the problem, he was going to pull the cam & lifters out of the 318, but at this point, that is not an option.

The kid is broke, with 2 little guys under 3, and he needs the ride to get back and forth to work, a 40 mile round trip.

He is looking for a motor to shove in the hole that will bolt to his 727 that will move the truck down the road as cheaply as possible. That 727 was rebuilt a couple years ago, the truck already has an electric fuel pump and a good SB radiator (if it didn't die with the block freeze). We know about the 318-360 converter difference, but what about the 318 converter to either Magnum motor?

If we locate a Magnum 5.2 or 5.9, what has to be done to make it carbureted, and what is required to make it connect to the things in his 78 Truck? Will the 78 distributor bolt into the magnum motors and work?

I have always swapped the complete drive train and installed the EFI, but he doesn't have that cashflow right now.
