Hey folks.

I'm knee deep in tearing down my 93 F250 XLT, 4X4 w/HD Suspension. I'm doing a full cab off the frame job, replacing the stock bed w/an Aluminum flatbed.

It currently has the 351FI Windsor in it, and this thing is completely beatdown. I'm debating wether I should replace it w/another gasser, or switch to diesel.

Tell me what ya think, Pros & Cons for or against one or the other. Don't wanna turn this into a debate. Just want opinions, to help me make a decision.

Thanks

 

Stick with a gas motor. If you rebuild or swap in another EFI 351W, you'll have no work to do but hook everything up. You can go to a 302, but I wouldn't bother.

Swap in a diesel and you're looking at a TON of work and expense, and you'd probably have to beef up the front suspension to boot.

 

I understand the TON of work part. Most of that's already happened. Bed/cab/gas tanks/drive shafts eveything is off the frame; except the front/rear axles & engine/trans combo, but those will be removed this weekend. As for the suspension, well that is already a heavy duty factory setup. All in all the work part doesn't bother me.

Just trying to get a good feel for the pros & cons of gas vs. diesel.

Well if you stick with a 351w you are looking at a direct bolt in of what you have. If you go to Diesel, the easiest one's would be a powerjoke, or a cummins. For the powerchoke all you need to do is find a donor truck's that been wrecked and pull everything off of it. If you go with a cummins it's about the same, but their are some parts you are going to have to roam the interwebs for, but it's a pretty common up grade to the superduty so it shouldn't be that hard to find the stuff. No I'm not a big fan of Powerstrokes. The 7.3 was alright but the 6.0 and the 6.4 is completely worthless if you ask me

I would say go with diesel for a couple of reasons.
1. "Free" fuel. You can run waste veggie oil, biodiesel, waste motor oil, ATF or just about any oil based liquid in it. It has to be conventional though has synthetic will just mess things up. There are pros and cons to each of these, WVO or biodiesel will cut power and millage buy about 7%, but run completely clean. WMO and ATF, etc. will actually give you more power but smoke. Although you could run about 20% WMO and still hardly notice it. And If you have two tanks, fill one up with #2 and the other up with the Biofuel and the government can't say a thing to you as it classifies as a additive then and you can run as much additive as you want.
2. Less parts to go wrong. You loose all the electrics off the engine.
3. More power with less money. As long as you can get more fuel and more air into it will make more power.
4. Will out last a gas motor any day. Diesels are designed to last forever.
That's just my .02
