My requirements... what to build?

Do you need a mounting bracket for this?
i thought i read where you mentioned this in another thread and there was something else that needed to be fabricated.

OD is not out of the realm yet. Just making the hard choice on the 318 or the 360.

I really need to talk to a builder LOL

There are adapters available of course to mount the transmission to the engine and I believe someone does make a cross member. US Car Tool maybe?
