Dodge Trucks

I have the chance to get a 75 dodge club cab shortbed 4wheel drive with with a dana 44 and dana 60 with lockers in both and 355 gears and a 318 with a 4-speed. I would like to know what other engines have the same bolt patten as it does not have pones for me what would be a good motor to swap in 360-383-400-440
