Nv4500 diesel swap

[harder93]

Can you swap a diesel nv4500 into a bronco behind a 289? I ask because I can grab one for 500 bucks and it comes with a gasser input shaft. Is it as easy as just swapping the shaft or is more different than that?

If I remember right there is more to it then just swapping the input shaft. The ratios change, so do the number of teeth on the gears. I can't remember if the input to countershaft tooth count stays the same or changes, I think it changes.

Yes!! You certainly can. I used the diesel one behind my 351. The only snafu is the clutch disk splines. Any reputable clutch shop should be able to get you fixed up.

... That's what I was going to say .. Yes just swap the shaft. as I recall ... And then get the correct spline for the clutch. As I recall the Pilot bearing was to large on the diesel one .... But Man $500.00 is a steal.

It's a 5 hour one way drive but I'd sure love to have one what clutch does it end up taking and what pilot bearing do I use?
