I have a client that is trying to sell me his Ford 400 block out of an old Bronco for $100. It's complete from the intake manifold to the oil pan. I did some research on the Internet and apparently it is based on the 351 block, but has tons of low-end torque. Is this block worth using in my FFR after the 302 dies? Will it fit in an FFR that was made for a 302? I couldn't find anything in the archives. Thanks for your insight.
