Wv Do you have the motor/trans mocked up yet? Remember that it is helpfull to mount the motor as low, and as far back, as you can. Sometimes we notch the MII crossmembers and box them back up to create more oil pan clearance. The bottom of the pan can be even with the running board. it will look small in the engine bay, but it will drive/handle better. Also, the low motor/trans hieght may solve your driveshaft issue. Try to keep the carb base level with the frame, crank angle will then be about 3*, then match the pinion.
Info search, I'll post up some book/web/chart info later
