I'm seriously considering using a JVX adapter kit and putting a four speed automatic behind a stock 375 HP 440. It looks like a 42RH or 46RH would be suitable. I know nothing about the torque capabilities of either unit. Would the 42RH be adequate or would the 46RH be a better choice? Again, keep in mind my experience stopped with the late 70's Torqueflite so this is all uncharted territory.
You have to cut up the torsion bar x member, bang on the floor board & make a custom x member.
