477 blown in '77 f900
I've got a 77 F900 tandem axle grain truck with the setback steering axle and the 477 motor. Well, this spring a connecting rod let go and damaged the block so it is unfixable. I have a 460 carbed sitti g around that runs great and isn't beig used. I was wondering if this would be a fairly simple swap, or will it be a complete PITA. Making/Re-using brackets for the front of the engine is no problem. Eve motor mounts wuld be ok. What I'm worried about is the bellhousing. It has the 3 range 13sp tranny in it with the low gears for the higher revving gas motor.
Any info would be great,
