You could maybe get a custom rear driveshaft made with the ball and trunnion (Rezeppa) type joint like FWD applications use. They will transfer power to almost 45 degrees and the old cross type ujoints can only efficiently transfer through about a 15 degree angle.

Not looking for a crawler gear, looking for better cruising rpm's. 3000 rpms at 65 mph is just crazy with a 400 c.i. engine.

If you're pulling 3000rpm at 65mph then why not just change to higher diff gears? 3.54 ratio would see about 2500rpm and higher than that would be better still.
I'm going to 3.54's from 4.56's, at the moment the 4.56's deliver a good 'relaxed' cruising speed of about 45mph hahaha.
