It has different pistons and rings and ring placement (industrial vs automotive), some gurus' think this is a performance advantage. I think the major differences are emmission reasons. . just my . 02.
The head is the old style and may have cracks in the valve seats, so pull it and have a good shop dip and magnaflux it. Also grind the valves and new stem seals at the least.
You may have to block off the fuel filter in the head if it doesn't use an inline p-pump. . may have to swap your gear housing and cover, which will mean pulling the cam.
You will likely need to reuse your oil pan and pick up tube.
Other than that everything should/will swap, did it recently for a customer (built up industrial short block, minus a cam 1991 vintage ( CPL 02304?)
Some times you can find a core out of a second gen truck that runs even for a $1000 or less. You will have your time and $1500 at a minimum to freshen it up properly. If the block is cracked, head cracked or warped then it goes up from there. .
Good luck. Andy
