Well time for surgery. If the block is busted then time to shop for a GEP longblock. If the short block is ok (unlikely) you could put GEP heads on it.

The GM 6.2 and 6.5,doesn’t have coolant in the intake manifold. Sounds like what happened is a fastener of some type fell into the intake port while he was running it open and got ingested and busted the head and piston.

Not really sure why I would want to turn a nimble warrior into a clutzy heavy slug that can be defeated with a coke bottle some gas and a rag. But that’s just me.

Looks like only the brake backing plates were swapped, not the entire axle. The main data plate says M246, manufactured by International. I do believe that truck is a 1950's manufactured truck that originally was gas.

Next time it hangs up, reach under the dash and pull the connector off the ignition switch, if it kills the engine you need a new switch!

Way too much current being drawn by the pump, if it burns up, well having a fire in a fuel tank cannot be good.

Standing water=soupy ground. You will know to stay clear next time.

I put JW Speaker military LEDs in all 3 of our FD LMTVs and everyone loves them. About $150 each on ebay from time to time. Flawless.

There is no rubber bushing between the military wrap leaf and the eye leaf.

That motor LDS427 had head gasket problems.

The one bug the multifuel trucks have is a tendency to throw rods. No rhyme or reason why.

If you are 100% certain you have good bubble free clean plentiful fuel flow to the ip and unrestricted return lines, and If you are 100% certain you have uninterrupted 24 volts to the ip, And your ip is over 10 years old, it's time for an overhaul.

Sure. You said: " I already checked gas tank, fuel lines from tank to pump to filter (put in a new filter) and return lines. All are good with clean gas. " Knowing this, the symptoms you describe (stalling, no power, sometimes idles bad) are those of a failing injection pump.

The heads are interchangeable. If you buy a used one, have it checked for flatness.

Your injection pump is shot.

The injection pump solenoid has to get 24 volts for the engine to stay running. The circuit powering this solenoid is completely unrelated to any circuits related to the 4L80E.

For sure 1964. For sure M543A2. Maybe USA number of 5D6804 (interpolated) Data snip from Carnac's Historical Thread. EDIT: I didn't look closely enough at the database earlier.

Oh I like that machine you have there, like a Swiss Army knife. We don’t have anything like that in the US.
