An 86 should be a 6.9L IIRC, unless somebody has swapped it out for a 7.3L along the way. The tranny in 86 was the nearly indestructable FORD C-6, they did not have the problems that the later electronic transmissions had with short life expectancy due to FORD trying to make them shift like cars. If it is a 6.9L, they are pretty gutless. Don't expect it to be a speed demon. They also have problems with the glow plugs in them breaking off and going through the engine best case scenario, worst case they take the engine with them. Only use BERU glow plugs(available at AUTOZONE under the MOTORCRAFT brand), never use AUTOLITES or BOSCH. Other than the glow plug issue they were pretty good vehicles, and you could always turbo it and make her run and pull respectable.
All the reading you could want on a FORD diesel.
