Just pulled the absolutely clean and spotless engine out of my 93 F-150. Someone had previously rebuilt it, everything on it was new, but obviously they screwed up somewhere. Had no compression in the #7 cylinder. Pulled the head to find a chunk of piston missing, and a gouge in the cylinder wall that a .60 over bore probably won't take care of. I have another engine for the truck. My question is rather than scrap and waste the block out of the truck, can that cylinder be sleeved, and be rebuilt to have a spare for the Mustang? Maybe even rebuilt as a stroker? Would I have the HO/non HO problem?

I've been out of the automotive game so long my mechanical wheels in my brain are rusty.

I'm assuming this is a 302?

302 blocks are a dime a dozen, sleeving it will be more than it's worth. (if it can even be done)

I have to agree. If it's just your everyday run of the mill 302 block, I'd junk it. If it was a Dart or FRPP block it may be worth saving, but I'd go find another one otherwise. My $0.02...

Also consider that the money you would put into sleeving it (if even possible) could just be spent on machining another block for a .30 over build/stroker.

I really hate yanking what is almost a brand new engine out of the truck, and throwing something in there out of the junkyard. But it's all I have the time or money for right now. The engine we pulled was spotless, there is NO WAY that engine has the 93K on it that the truck has.

Man what you should do is go to carpart.com and look in your area for a low mileage Explorer engine. I've seen 60k engines sell complete for $500 and less. That'll give you almost 100hp over what you probably have already. I know guys running 12.50s on junkyard engines. You might not be racing it but to me that says they're reliable enough for a daily driver.

Tore the intake of the replacement engine today to find tons of sludge and dirt all through the engine. No way I'm putting this thing in my truck I'm considering, if possible, yanking the engine out of the Mustang for the block, and just buying a crate motor for the Mustang some time in the future. The Stang can wait, the truck I need now. Is it possible?

Is this the same engine or another junkyard engine? (the one with all the sludge).

This is the engine the dealership (used car place) gave me to replace the blown one. This is cut and pasted from a blog of mine, explains it a bit better.

Bought my truck last year, one I've always wanted, '93 Flareside F150, 4x4, 302. The engine blew 3 weeks after I bought it. The dealership only gave a 30 day warranty for up to $200 worth of repair. I took it back, and knowing that my brother is a mechanic, and that I'm not too shabby working on vehicles either, they offered to buy me and engine, if I put it in myself. Sounded good to me. The engine that was in the truck had no compression in the #7 cylinder. The engine is super clean. Well, once I pulled the engine out, and pull the head, I find the edge is broke off the #7 cylinder, and the cylinder wall is gouged so bad, a.60 overbore won't fix it.

So on too the engine the dealership gave me. Some surface rust...not too bad, I'll just use all of the upper half stuff from the other engine.

NO SUCH LUCK.

4 manifold bolts broke off in the block, tons of sludge and build up in every port, this is easily the dirtiest, filthiest nastiest piece of **** engine I've ever seen the inside of. Looks like they used dirt for oil.

So here I am with 2 engines for my truck, neither of which I can use...and still stuck driving my wifes little escort around....

I almost bought an Explorer engine once but didn't have a place to store it. I went to the place that was selling it and the engine was still in the truck and showed the mileage...that's what you want. Any engine that's already out of the vehicle they can tell you anything they can make up.
