I am considering swapping a 318 Magnum motor out of a 1996 Dodge truck in place of my ’79 Diplomat’s tired 318 LA. I need to know if the transmission will bolt up and if the motor mounts and oil pan will transfer from the LA to the Magnum.

Trans – yes.

Mounts – yes. Pan – no.

The reason that the pan will not swap is that 318 Magnum engines used a 360-size rear main bearing cap O.D., one reason the factory did this was so 318 and 360s could use the same oil pan. MP sells a pan that will do the trick — a 360 passscar pan. If you’re going to all this trouble, I’d sure use a complete 360 Magnum…just my 2¢ worth.
