Default Diesel conversion?

As my 1994 F150 Flareside 5.0l v8 with 4R70W auto trans. approaches the need for an engine rebuild (205k miles), I have a couple questions:

Has any one converted from a 5.0l V8 to a diesel? If so what is involved beside the engine & what can be salvaged from the 5.0l? Long shot obviously!

What is a better direction for a very lightly local use truck;
A re-manufactured block or having the lower end redone with new fit bearings (low oil pressure when engine is at temperature)? I can handle the latter, but a new block would be farmed out.

Thanx Lobo

I helped a buddy do a 460 to powerstroke swap in his f250 and I don't remember keeping anything in the engine bay except one of the batteries. I can't imagine it would be any easier starting with a 5.0. Easiest swap would be a 351. There is a guy in here who did a 460 MAF conversion on a flareside, but I can't remember who off of the top of my head.

That's a beautiful truck.

a lot depends on just which diesel you want...we did a Cat 3208 back in the late 80's. A friend did an early power stroke in his 92, and other than the time and cost, it plays very well.

Were it me, I would go with a new Ford crate motor and be done. Weekend job DIY.

all the best no matter what you decide

I've read cummins swaps aren't too difficult(in the grand scheme of putting an engine into a vehicle that wasn't designed for it). Some manufacturers even make mounting kits for them.

Have you tried just running diesel to see if it will work without any mods?

I decided for my limited use a new Ford crate engine is the best choice. I don't put 2,500 miles a year on the truck.

Thanx to all,
Lobo
