This is the 97 Ford F4TE Roller Cam 351W combined with the 1995 Chevy NV4500 and BW4401 Transfer case, also the rear Dana 60 before the rear drum to disc swap. The 351 came with E7 heads that I will reuse. It will have the 70 Mach 1 4V intake and dist from one of my old mustang projects. I will retain the serpentine belt system also.
