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. tom w

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.
