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

I had one from canadian high performance discount, but i'd imagin Jegs, or summit would have them.
it would be the same as a bop-chevy adapter.

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.
