conversion

Ok, stupid question can I convert a 345 or 392 gas engine to a diesel or would it be more economical to drop in a older 7.3 diesel in>
 
It would be "more economical" to buy a Ford pickup with the diesel already in it...

Since you seem to be on a budget (and not very experienced) based on your previous posts, this post is "pretty stupid" -- and a waste of time... Unless that is really the point of your post...

Gas engines are gas engines; diesel engines are diesel engines.

There is no "conversion" -- though GM tried in the late 70's / 80's -- cost them a lot of money -- and customers...

If the idea is to make your 'binder run on diesel, the only practical way would be to repower with a different engine.

Converting a gas engine to run on diesel is just not a very practical way in which to run on diesel.

There have been some gas engine that have been converted to run on diesel but the bottom line on all of them was they were very poor performers.

Greyhound converted the continental powered apu that ran their a/c systems from gas to diesel. Since they ran at a pretty constant speed it wasn't such a bad idea--only one fuel tank and no gasoline in a bus. But starting them on anything but a hot day was not fun.

GM built the toroflow in the early '60's. It was based on the gmc truck gas v-6 engines and were not much good for anything except for boat anchors.

From that experience GM built the 350 diesel based on the oldsmobile 350 v-8. I think you would be hard pressed to find one that is still running today.

The bottom line for converting from a gas engine to a diesel engine is why do you want diesel power?

On a good day, the best you can expect in fuel mileage gains is a doubling of your current fuel mileage. The more likely increase would be in the 20-50% range.

With diesel fuel at or above the current price for regular unleaded gasoline the break even point for a diesel engine conversion is somewhere out in the 100-150k mile point. And that is not even considering the fact most diesel engines use twice as much oil with oil filters that cost twice as much, twice as many fuel filters that cost more than twice as much, and air filters that can cost as much as 10x as much as what is currently used on your 'binder.

Repowering from your current 'binder engine to any kind of diesel engine is not going to be a bolt in affair. It is going to require some sort of fabrication for engine mounts, radiator changes, transmission/driveline adaptors and changes, and fuel tank plumbing changes.

I have included a couple of posts from over at just internationals Of diesel power conversions done by csmith. As you will see, it isn't easy to do a diesel power conversion unless you are more than just a little bit handy with fabrication.
