you will need all the sensors, wiring (engine) loom. You will likely have to make up motormounts and you'll need a front sump oil pan if its a rear sump(along with pick up) I'm not sure if they made the 3.8 with a front sump, but you could search around or make one up. You will need high pressure fuel line, one for delivery and one for return along with a good inline fuel pump (high pressure) For exhaust..... not sure on that you could try the factory manifolds to see if they are close, otherwise get a pair of aftermarket headers and see if you could "make" them work. Worst case....custom headers. Personally, i like the idea of the 3.8 SC motor in the pinto, i wanted to do that to my father inlaws '78 coupe. This is just a first thought reply...i'm sure i'll think of other things later.
