The big thing with the 5.0 efi motors, is the design of the EFI intakes. They use a very long runner, to make alot of torque for the size motor they are. For instance, the 5.0 H.O. in my mustange makes 225hp@4000rpm. and 300ftlbs@3200pm. The main reason for this is the long unners.
I would say forget the bronco motor and go for the H.O. I paid $200 for a running lincoln mark VII had a 5.0 H.O. with 165K on it, not even broken in.
Also the H.O. motors have a roller cam, and forged pistons. You can find them in 87-93 mustangs, 86+ Lincoln Mark VII's and in some thunderbirds..
