Free 440!!!!

I got a free steel crank 906 head 440 on Seattle Craigslist. I think the manifolds won't be a good idea, and is the trans the same as a car 727? Are the manifolds logs or center dump? Try B-body HP manifolds if going that route. I've seen RV transmissions be different that passenger car transmissions. Some have a parking brake in the tail shaft, and some have a short tail shaft.
