I have a 1949 f2 and I want to put I a 1988 7.3l non turbo diesel in it . It's efi and I want to convert it to carb because the person I buying it from just has the long block but no electrical with it . So how hard is it to convert to carbureted ? Any body have some pointers all help is appreciated thanks in advance

 

Impossible.

 

Those diesels run off mechanical fuel injection. The only electrics needed would be for the fuel solenoid, glow plugs, and starter of course. There are plenty of diagrams on line.

 

Alright thanks I guess I was just miss informed

 

Yeah. You'd first have to "convert" the engine to a gasoline engine. Which would require changing the compression ratio among other "things".... anything's possible with enough money!!! (just not worth it!!)

Actually, the 6.9L and later 7.3L engines are loosely related to a gasoline engine originally designed and built by IHI

The 1988 7.3L injection system is NOT electronic. It's a Stanadyne DB2 mechanical injection pump. Very simple and reliable.

If you want to put 7.3L (or a 6.9L) non-turbo engine in your F2, it would work well and get pretty good mileage. You could also bolt it to either a C-6 automatic or a ZF 5 speed (with OD...which would even be better)

Main problem might be the left exhaust manifold interfering with the steering box and the weight.

You would nee a LOT more than just the pump though. Intake manifold, injection lines, injectors, etc.....

It would be better to get a running "take-out" engine.....

 

That 7.3 is VERY heavy, too, not sure an F-2 would be up to it. The stock drivetrain sure won't last behind it.

 

I'm no diesel expert just know the basics and Rick from above is probably better suited to ask about them, but I would think that the cummins 4bt four cylinder diesel would be better suited for your application. Weighs in at around 750 lbs. (7.3 close to 950 lbs.) , About 31 inches longPretty easy to find around here in old bread trucks.

 

I'm running a cummins '6at' 6 cyl turbo diesel in my '59 f350. About 700 lbs and 33" long. Built in the late 80's and used in UPS and frito-lay trucks. I have come up with 3 of them in the last few years. Only 120 hp, but excellent mileage and excellent turbo whine . Cummins still stocks the parts. They were used on generators for many years before they came out with the automotive version. Easy installation and uses any gm tranny without an adapter. Two ways to see my install. youtube.... 59 f350 with cummins 6at....... and My build thread on the 57-60 section called ' kinda like a hot rod but it isn't hot'. It's been a very useful and practical truck.

 

GB, what kind of mileage do you get?

 

17.5 mpg on a 165 mile trip. Half freeway 65 mph, half winding two lane. Keep in mid it's a heavy one ton truck. I recently bought an '85 mercedes naturally aspirated diesel wagon for a thousand bucks. My wife is using it for her commute. I'm pretty impressed with that 5 cyl 3.0. 27 mpg on my first run to Seattle. Loaded with tools and 75 mph most of the way. I know one of the guys here put one in his half ton and made a run to Alaska, so that's one to consider too. I need the extra cyl on the cummins for the load hauling and trailer pulling.

 

Yeah, but you are absolutely right! A 4BT would run well in an F2 (although not as powerful as a 6BT~~1100lbs!)

I thought about using a 6BT in my F-600 too! but a 292 with dualexhaust sounds better!
