My brother died last year, he left me with more projects than I need. I have enough of my own. I need to move his 86 F350 out of the shop. After 10 or so years it's time to go. He was going to fix it some day. Putting the front end back in without the gears just to move it. Not sure of the motor size. How can I find out? The motor has a Banks Turbo, are they that great, or just something else to give me a problem from setting? Stan
 
If it were mine I would get the VIN off the dash or driver's side door panel and plug it in the link below.
This assumes he didn't swap out the engine;-)

Motor should be a 7.3 IDI. First year of production. I would tell you that the Banks is not a good idea unless the engine was rebuilt to handle the turbo. Others will tell you there's no problem.
 
With a Banks turbo, it must be an IDI diesel. The 7.3 IDI came out in 1988, this truck would have a 6.9L unless swapped out. The 6.9 was a good engine but had a few flaws (glow plug system, heads/gaskets), The Banks turbo was the most popular add-on turbo system for the IDI. For their time they had decent power but not 460 gasser power. The turbo helped a little but not a lot, they were still turds back then and definitely are by today's standards.

There were basically 3 versions of the IDI. 6.9L, 7.3L n/a, & 7.3 turbo. The 7.3 turbo was only in 1993,1994. The turbo engine looked identical to the n/a 7.3 but is had various internal upgrades, along with different injectors and injector pump.
 
it SHOULD be a 6.9, but yeah, they get swapped out a lot. If you cant find or read the decal on the valve cover, look at the relay for the glow-plugs, at the rear drivers side of the intake manifold. If it is a weird looking cylindrical pipe-threaded gizmo, thats a 6.9. If it is a plastic box-like contraption (sometimes still under a form-fitting plastic shield) bolted to the manifold, thats a 7.3.

You can also take off a handy-to-reach head bolt. 6.9s have 7/16 diamtere bolts, 7.3s are 1/2 inch.
