440 4spd o/d

[cannonfodder]

I need a flywheel and bellhousing to mate a 833 od to a 78 440 with the cast crank. I realize there probably isn't one. Any advice?

[Speed Dragon]

Flywheel is the same as a 318. As for the bell, you could have the hole machined out to fit the 833-OD's bearing retainer.

Are you sure on the flywheel?... I thought the 440 was externally balanced wether cast or forged crank,
My thought was to go with a scattershield since the big-block bellhousing is dificult to locate. This does limit you to a 10.95" scalloped clutch since scattershields are desigen to fit cars. My last thought was ebay, look in "Mopar transmission" to get a start.

I think the flywheel is out of balance also. It says cast crank only on the harmonic balancer.The small clutch will be fine for a while as it only has about 250 hp. I only have a 6 cylinder flywheel now.The steel bellhousing may be the only way to go. Are there aftermarket cast crank specific flywheels?

[Speed Dragon]

I've always seen flywheels advertised to fit 273-440, except for the 360 and 400, which are externally balanced. I'd be checking the engine size if I were you.

[cannonfodder]

It's a 440 alright. They had to externally balance the engine starting
in 1972 or 73 because the cast crank didn't weigh as much as the forged one. It's easier to find a forged crank than a cast one but this is a low milage rebuild I bought out of a motorhome. I thought I would run it for awhile,at least until I managed to blow it up with hopup addons Roller cam, headers and single plane intake will test the bottom end. With the 440 and o/d with 4.56 gears I thought it would be a fun combo in my shortbox fleetside D100

I bet if speed were to look at the footnotes for 440 it would say "for forged crank only". The 360 and 400 have cast cranks and for this reason are externally balanced do to the extra material needed to provide enough strength, compared to that of a forged crank.

Still then he should be able to use a 360 flywheel right? If so, 75 PowerWagon on here has one for sale.

[cannonfodder]

From what I have read they were all balanced differently and there was even a cast 340 crank in 73.

I have a 360 flywheel a 400 flywheel for a 12" clutch and cast iron and aluminum bellhousings for a 440, Also a big block 4x4 4spd bellhousing. give me a pm if your intrested in any of the parts....

[B-300]

Cannon,
Your correct about the 340 cast crank also belonging in the list of what is known as a "detroit balance".... The other list would be neutral balanced engines.
I don't think the 360 and 440 cast crank have the same imbalance, but I could be wrong.

[cannonfodder]

I'd like to have that aluminum bell if it is for an 833 But you're a long ways away.

[Speed Dragon]

I guess the thing to do would be to call up Mopar Performance, they'll be able to tell you for sure what flywheel will work. I always thought they listed that stuff as interchangeable between ext. balanced engines, but I could be wrong.

Flywheels WILL NOT interchange between small Blocks and big blocks, either internally balanced OR externally balanced. ALL B/RB big blocks 1973 and before were externally balanced. Also, about forged cranks, beginning with the 361(DO NOT CONFUSE THIS WITH THE LA-SERIES 360 SMALL BLOCK-ABSOLUTELY NO SIMILARITIES!) in '58, to the 440 all the way through to 1971, were a stage 1 forging. In 1972-73 mopar engineering developed a stage 2 forging which was heat treated to make it stronger. These are MUCH HARDER to find and MUCH more valuable cranks. Either way ALL forged B/RB cranks were internally balanced, then beginning in 1974, ALL the cast cranks were externally balanced. To cut production costs, of course.

[Oldblue1978]

In the first part of my post I meant that 1973 and before were INTERNALLY balanced. SORRY!

[cannonfodder]

After lots of reading and surfing it appears the 400 and 440 cast cranks are equally unbalanced and the flywheel will interchange. There is a local shop which rebuilds 833s and sells MacLeod bellhousings, flywheels and clutches. I think I will get a quote on the whole package and no doubt get it new so as to avoid mismatches.

[Oldblue1978]

Yes that much is true but remember, the 400's flywheel is lighter than the 440's because the 400 is, like the 383, a low-deck big block, and the pistons are around 200 grams lighter than the 440's. Anyways whenever you are doing interchanges, the only way to do it right is compare. Even if the motor originally had an auto they are still balanced the same. You'll need to take the weights off the original flywheel and weld them to the new one. That's what I did many years ago on my last project. It was a '73 Power Wagon with a 440.
So how far along are you with yours?

[cannonfodder]

I get the truck with the 4 speed in it in a week. The 440 is setting in the garage with an automatic on it. I'm going to pull the 6 from the truck and install the 440. Once I get everything to fit I will get the 4 speed rebuilt. I figure it will need to be in top shape to withstand even a low performance 440. I expect the 8 1/4 rear will be the first thing to explode.

[cannonfodder]

Sounds like a great deal to me.

[rentacop13]

well now that i don't feel like i paid too much anymore i have a question. what is the difference between a dodge truck in those days the 100 series and the power wagon? what makes a power wagon a power wagon? : :gr_patrio

Yep I agree
