I don't think there's a BOP bellhousing tranny with overdrive other than the TH200-R4 /forums/images/graemlins/tongue.gif

When I worked at a wrecking yard, one of the guys made a bellhousing adapter (to run, say a TH700 on a Buick/Olds/Pontiac) out of 1/8" steel plate. The plate has both the BOP and Chevy bolt patterns on it. The four lower holes just get the usual bolts through it, while the upper holes on the Pontiac block and Chevy tranny get bolted to the plate itself. Then use 1/8" thick washers between the flexplate and torque converter.

You can also buy that adapter plate through places like PAW. But you are right, no BOP 700R4.
