Gen 3 Hemi Swap time!!!

You've overlooked a well built 200R4. Holds over 1000hp, requires only the notching of the torsion crossmember and bolts right up to the new Hemi's. It's also available with a lock-up converter that is controlled with one 12v wire. It also is much more efficient of a design than the Mopar overdrives, and takes less power to spin.

Either way you go, it sounds like it will be a fun car.
