The adapter will work with that tranny. I used the Jegs adapter on my BOP th400 tranny. Removed the 225, bolted up the adapter to the bellhousing (leaving the old 225 adapter on it) and the 4.3 bolted right up. I pulled the 4.3 out till I have the time to rebuild it with an RV cam for low-end torque, fab new motor mounts & some other stuff thats needed to be done. Then it'll be going back in sometime around april or may.
