Ok now I can report back with an update on my problem as I just picked up the truck from the mechanic tonight. We replaced the old tired 283 with a newer, stronger, and fresher 283. Same setup as the old one, stock heads, Holly 600, Edelbrock Performer intake. Went ahead and replaced the Rams Head driver side with a 265 log style manifold. We lifted the engine just a hair to where the manifold just sits ever so slightly above the stock steering box giving me the clearance that was needed to keep the stock steering without moving anything. This also straightened up my motor as it is centered in the engine bay now. That kinda moved my alternator too close to the fender. I ordered a stainless lower alternator mount that puts the alternator where you would normally see a power steering pump. We also got rid of the offset front motor mount and was able to set the motor at center on side motor mounts on the new cross mount. This also allowed the tail shaft to be properly mounted to the tail mount with 4 bolts, 2 up and 2 down as designed. Test drove it and the drive train is smooth with no vibration. Had to utilize a flex hose to hook up a temporary exhaust system on the drivers side but will take it in to the muffler shop sometime next week to fix this problem. Also replaced the universal joints on the drive shaft with fresh ones since everything is straight now. Still going to have a drive shaft safety loop installed for my piece of mind. Also during the change out it was noticed that the 12.85", 153 toothed flywheel had damage to 4 teeth we decided to change that out as well. Still have a positive pinion angle but it does not seem to affect the drive shaft as much since everything is straightened up. Will put this repair on my to do list soon. The new 283 runs about 60 PSI at 60 mph and about 27 PSI at idle under load. The old 283 ran about 40 PSI at 60 mph and 7 PSI at idle under load. The old motor also had a knock maybe wrist pin or main bearing. The newer motor also has new front and rear seals. We replaced the rear transmission seal as this should take care of all my leaks. All in all it was a good day got to take it out on its maiden voyage. Thank you so much for all of your inputs as it helped me out a lot.
