    Is this possible. Is there an adapter. I just got my self a 500 and I want to run my 700/241. Is this going to be possible?

    Yeah sapters are fairly cheap. but i dont think the beefiest 700r4 will last behind a caddy 500, even stock.

    I was going to run a raptor 700 or a bowtie overdrive. They say it will hold. Where can I get these adapters?

    A professionally built up th700 will do just fine behind a stock or mild caddy 500. /forums/images/graemlins/thumb.gif

    Why not run a 700R4 from a pontiac,buick,or oldsmobile--they already have the same bolt pattern as the Caddy--I think they might have some with the "Unibell"bellhousing with both GM bolt patterns in it also.If not,the adapters are about 60 bucks from Jegs or Summit.I think a good 700R4 will last behind a 500,if you dont whale too hard on it,and run a good cooler,its no TH400,but it should be ok for light to medium duty use--just dont do brakestands or tow heavy trailers and it should live--. /forums/images/graemlins/crazy.gif

    IIRC, the 200R4 was the BOP tranny. I don't think a th700 was ever used behind the BOP motors, could be wrong though.

    I stress again...a built up 700 will last just fine, brake stand, pull heavy loads, what ever. I pull some heavy trailers behind my K5 with a built 406 in front and relatively tall 4.10's/35's.

    No such thing as a BOP 700R4 unfortunately. 2004R was the unicase (and/or BOP only) OD tranny, and can't be used for a 4wd swap. (easily anyways)

    What about the flex plate to torque converter? what kind of spacers would you use for that?

    for a street rig this might work... but I'd be worried about toasting 700s with regularity if you really use the rig hard. 500 caddy is a whole lotta motor. Toss a TH400 in there and be done with it.

    There is a reason these motors came backed by TH400's in the Factory. For the sake of peace of mind (unless you really baby your rig), I would strongly recommend a TH400, or 4L80e.

    No pro on this, but I believe the torque converter bolt patterns are prtty much all the same. Some "dual pattern" flexplates, but I believe that was on the TH400 flexplates.
