Its a standard square bore intake. You can get adapters for square to GM TBI. Then bolt on TBI. GM actually made a adapter for spread bores as they had left over carb intakes for 454's when they swapped over to TBI on them so they made a factory adapter.
Then you have to modify the distributor for the magnetic pickup, add a electric fuel pump. And burn a chip for it.
The SV (304,345,392) Parts are pretty common for the motors as IH used them in the S line up threw the 80's so lots of parts for them. Pickup truck production ended in 1975 and Scout II's in 1980.

Actually NO. The 5 speed originally were built by Fuller in the 60's. IH acquired the design, tooling, etc. for the 5 speed from Fuller and moved the manufacturing to Fort Wayne, IN. The 5 speed went thru several design changes in the 20 or so years it was built by IH various ratio combos etc. The company also made its own drive axles for some applications which many mistake them for eatons when they are infact IH built. The IH transmission and axle business was sold to Dana / Spicer in the mid '80's. Dana continued to build the 5 speed for IH / Navistar trucks until the early '90's when it was discontinued.
IH did use B/W trans, but the 5 speeds were in house built.
It has a 12'' mechanical clutch.

Does you NP205 have the choice of 2wd/4wd in both high and low range? Or is it still a full time drive box?

It has 4.56 gears. The NP 205 is a divorced unit and is a single stick so high and low range. It was never used as a full time transfer case by IH. IH had there own chain drive single speed transfer case used in the trucks and Scouts.
