I have taken a few years off from building mopars after retiring. Couldn't stand it, and bought a promising project.

It is a 318-2, Short bed, automatic and everything mechanical is in tact other than missing air cleaner and butchered carb swap.

It hasn't ran in years, all of the potting compound in the ecm, voltage regulators have melted and ran down the firewall and the wiring has been messed with.

Floorboards are on order. Someone had already grafted in some metal and used home expanding crack sealer for the gaps.

I have started taking this rig clear apart and am considering a Gen III Hemi swap.
Will it bolt up to the existing trans/transfer case set up? Has anyone done this?
