4 cly diesel and 5 cly diesel weight

Hello, Can someone give me (or tell me where to go to get) an approx. weight of a complete pullout 4 cly diesel with a 4 sp. manual trans out of a 1979 240, and the weight of a complete pullout 5 cly diesel (has turbo) with an auto transmission out of a 1984 300?

I'm thinking of installing the 4 cly diesel in my 1934 Ford PU. If the 240 weighs about 3200# complete and my '34 weighs 2750# with the flathead, I'm thinking the '34 PU with the 4 cly diesel,4 sp. trans and rearend out of the 240, should weigh about the same or less than a stock 240. Wonder if it would give me 30mpg? Thanks, Joe.

Nothing definate

but I've read on here that the 5 cyl. diesel (just the engine) is about 450 lbs, and the auto trans is around 175. I know the manual trans is a lot lighter than the auto. I would think the 4 cyl. would be a little more than 4/5 the weight of the 5.

No guarantee on any of these numbers.

On edit:

If I had all that stuff, I think I'd leave the flatmotor in the Ford and assemble a turbo 5-cylinder/4spd '79 240 (assuming you aren't parting it because it's in "parts car" condition).

i wouldnt think

that the drivetrain from the 240 would weigh much, if any, more than the ford drivetrain. those flatheads aren't all that light. as far as getting 30 mpg, i dont know. the ford looks a lot less aerodynamic, to me. i think it would depend on what speed you drive. if you cruise at a pretty sedate speed i think 30 is possible. i dont know how to calculate it but i would think somewhere between 55 and 65 would do it. the wind resistance increases by the square of the speed.

if you spend most of your time around town then i think it will get the same or better than a stock 240. i think it will be a bit lighter than the 240 when complete, depending on what you include in the car such as power steering, ac and such.

it would be a cool ride though. it would be the envy of all us diesel nerds and geeks.

The rear end ratio in your Ford will also have an impact. I think they ran 4,10:1 gears, unless there has been a change. IIRC, the flathead weighs about 600lobs. The 240/manual should weigh less than that.
This sounds like an interesting conversion; keep us posted.

rearend

Haven't checked the gear ratio, but it should be o.k. It's off an 80's camero that was a v-8 and automatic. This truck is an old project I started years ago when gasoline was cheaper. If I can cruise at 60-5, I'll be happy. It will be mostly a parts chaser around town with an occational 80 mile run now and then. Let you know how it goes. Thanks,Joe.

it sounds like fun

i would like one like that too.

in fact i have been pondering building one based on a 29 or 30 ford pickup. light, pretty and usable especially around town.

That's exactly why I bought the 240. I have a '29 PU that I wanted to put the 240 drive train in, but decided that I liked the '29 with the original drive so I left it as is. In the meantime, this '33 project had been on the back burner for about 2 years with out a motor or trans in it. It already has the camero rear in it. Was going to go with a '96 vortec and 700R, but with the price of gas going up, I think that it would be neat with the Mercedes drive. I may try putting the 240 rear in it, that way all the drive train will be 240. Joe.

usig

the 240 rear end is a good idea but it will be tricky. there are links near the outer edges of the body near the rocker that will be considerably past the frame line on the old truck. an independent rear will make the truck ride a lot nicer. there are other rear end assemblies that might be easier to transplant like a jag unit which comes in a complete unit that can be unbolted and attached to your frame, as i remember.
