4.0 Rebuild

I think the only differences are the cam,and injection but there could be more.

The 4.0L up though '90 was the Renix design. '91+ 4.0L HO has a redisigned head that produces quite a bit more power, a different 'puter, and other minor changes.

the head has a much nicer flow design in the HO
