Do the Diesel Trucks that had a 700R4 use the BOP bolt pattern?

    I'm thinking of doing a Cadillac 472/500 swap, and am wondering about how to put a 700R4 behind it. (Please don't get into the "700R4's are Junk" thing here, I've been through it a zillion times before...) Of course there's the adapter plate, but I am certain that 700R4's came from the factory with universal and/or the Buick/Olds/Pontiac/Cadillac bell housing pattern. This would be true of both 4x4 and 2x4 versions right?

    I base this all on the fact that I thought the 6.2L diesel was based on an 0lds block. Am I smoking something or am I on track here?

    Thanks,
    Paul

    The 350 or as they called it the 5.7l diesel was based on the olds engine and yes was a BOP pattern, and they came mostly with the th400 and th350. never seen a 700 behind those but I have seen a 200r4.
    Now the 6.2 was designed as a clean sheet and no was not based on the olds engine and has the chevy pattern.
    I can't tell you if the 700 4x4 has a universal p[attern but I know that the chevy pattern later became the universal GM pattern.

    As Iceman said, you're thinking of the 5.7L diesel, which was based on an Olds block. The 6.2L was designed from the ground up and shares nothing with the gas engines. Both the 6.2L and the 700 tranny were introduced in 1982, and both use the Chevy bellhousing. I don't know if there were 700's with a BOP pattern or not. I believe the 200's did.

    There was never a BOP pattern 700R4 from what I have read, but the best place to look for one would be in a mid eighties RWD car I guess. You won't find one behind a 6.2L or 350 diesel since the 350 diesel ended before the 700R4 came out.

    That $70 adapter kit from Jegs is probably the best and cheapest way to go. Comes with everything you need to make it work and is only about 3/8" thick.

    I don't know where you got the 85, 85 sure didn't have a 5.7 diesel.
    All the litterature I have show 81 for the last year of the 5.7 diesel on the GMC or chevy trucks.
    I don't know about the cutlass, I do know they had the 4.3 in those, I don't believe they put a bigger diesel, and if they did it would have the 200r4 not the 700 since they didn't make to the best of my knowledge a BOP 700.
    Now something will come out and prove me wrong :D

    Well i just found that up to 85 the 350 or 5.7 diesel WAS offered in the Cutlass supreme, but again that came with a 200r4, I had one of those with the 307 gas engine and the 200r4.

    The 5.7L diesel was available in full-size Oldsmoblile, Cadillac, some Pontiac, and some Chevy CARS from 78-85. The 5.7L diesel was offered in 1/2 ton Chevy and GMC pickups from 78-81. In 82, the 6.2L diesel was introduced in the truck lines. The 6.2L was offered in the trucks while at the same time the 5.7L was available in some cars until it was phased out in 1985.

    I'm sure Kenny was thinking about the truck lines, when the 5.7L diesel option did, in fact, end in 1981. He probably didn't realize that you could still get one in the car lines up until 1985. Still, you could have rephrased your reply to a be a bit nicer, now couldn't you? :crazy: We're all here to help out and learn what we can....no need to get snobby about the whole thing....life's too short, eh? :cool1:
