6 pack Balancer?

[Thunderdan]

Picking up a Class A RV 440 engine (i believe it's a '75 model) and was able to snap a (poor) photo of the balancer from the underside. Any way to tell if this is a balancer for the HD rods or might they be the standard LY units?

it is too thick and too small in diameter Compared to a pass car balancer.

It looks like an LY rod motor to me. Might be a steel crank too.

Industrial balancer per 440source site it appears

Shown above is damper #1858382, used on heavy duty (HD) trucks and motorhomes with internally balanced forged cranks. It measures 6 1/4" diameter by 1 5/8" wide. These first came into use in 1960, when the heavy duty/industrial versions of the 361 and 413 replaced the early hemis (354/392, etc) in Dodge's medium and heavy duty lines of trucks. They continued to be used unchanged until Dodge discontinued their medium and heavy duty truck lines in 1977. All of the these balancers have the standard offset pulley bolt pattern. The hub used on these units spaces the pulley out further from the engine, so if one of these were to be used in a standard car-type setup, it would require a custom pulley arrangement. Also, note the lack of a hub which overlaps the outer ring, acting as a safety to keep the ring from flying off. Also, these are always used with timing cover #1858639 (our part number 100-1063) These use the long damper bolt.

Thanks for the responses, Guys. Will be getting it pulled and broken it down soon enough to determine the specs and condition. Staying hopeful, but realistic with expectations after the RV last being registered in '98.

You probably will find using that damper will be a pain to get the pulleys & miscellaneous pieces to line up, time consuming, possibly expensive. Think about clearance to the radiator also.

Make sure it's a passenger style 440 first, and not a 413 industrial, as it would appear.
Simply looking at the top of the motor will easily confirm.

True, however it can be replaced with a standard modern replacement to work with my car's accessories. If it's a steel crank, then just a bonus on the package.

Checking it out later today and may have more pics to share. It's a HD engine for sure, but TBD on displacement.

If it's industrial... about all you get is a smallbore block and possibly 8 connecting rods...

I've passed those up before

The 413's, while admittedly having a slightly smaller bore than a 440, were no slouches with the right heads, cam, and compression. Decent starting point for a build with the beefy internals to start with and good aluminum heads are affordable. Piston are not gonna be cheap though.

Haven't pulled the engine, but he's a couple of (admittedly poor) pics of the engine from the cramped wheelwells. Access via the doghouse to identify engine pad is impossible due to junk crammed in that will be cleaned out in the next few days. It's newer than a '72 model so I'm confident it's

a 440, but can anyone tell if this is a conventional truck engine or if it's a legit industrial engine?

 

[furious70]

Can't tell 100% but those look like the industrial exhaust manifolds. Only the short block would be useful

I'll take a steel crank (hopefully low mileage) 440 shortblock all day long, lol.

I would too, but sometimes (all?) They have a different crank flange. I would take a look at the converter/ crank area. Lot of time and work for fuckall if it's of no use.
Could sell it to a motorhome guy I guess.
Would like to see it pan out for you.

 

[RemCharger]

Just did a quick search on it, sounds like 50 50 chance on the crank. But nothing on any 440 industrials. Just 413s. Made em till 79.

 

[R413]

That is an Industrial engine.

 

[Thunderdan]

Good possibility it is, but I'll pull it and see. As @RemCharger mentioned some had a thicker 8 bolt flange on the rear of the crank, but this one' connected to the 727 still so I suspect it's standard. Again, we'll see, but the price so far makes this a worthwhile adventure to see what's up.

 

[R413]

I can see it now so I thought I would tell you: differences in cylinder head design, exhaust manifolds and spark plug positioning.
