if its forged, does that mean it is externally ballenced?

The 413 industrail pistons are really heavy, very thick tops and a full dish to boot 
The first forged steel cranks that where externally balanced where the six pak rod Magnum 440 in 1970,1971 and some 1972 perhaps also, I think 
what are you trying to make or use that crank in?

Re: 413 industrial - 09/13/12 06:26 AM
the crank stays with the motor. The 413 industrial is being mated with a np445 4 speed truck box and np203 tcase for my 76 pwagon. my concern is WILL IT SHAKE THE CRAP OUT OF ME?. i want to make sure its properly ballanced before buttoning it up. the industrial came out of a 72 dodge commander rv, the flywheel came from a 76 400 truck, and the tranny and case came from a 75 pwagon

It wont shake as long as you use a neutral balanced flywheel. Be ready for twisted U joints. Those 413 Ind morors are torque monsters.

All the 400 and 360 flywheels are exteranlly balanced 
Have it nuetral balanced before using it, look at the crankshaft bolt pattern to make sure the flywheel will bolt up to your crankshaft 
. It should be a 6 bolt crank pattern but some of them are 8 bolt like the early motor where

with cab. 400 would be a cast crank which used an external balance flywheel.

I think you'll find that some 400 4-speed cranks were forged and are internally balanced...basically the same forged crank found in the 383.

Unless that 383 is a cast-crank '71. Sorry, John, hadda say it.
I would think that a 72 motorhome 413 would have a std 6-bolt crank flange and NOT be an industrial. Does it have the funky waterpump hsg that feeds into the heads?

I believe industrial 413s had an 8n bolt flywheel flange and a lot of the front end would not be used in a light truck or car application . The heads are diff and the cam spins opposite to the crank. Some other things are diff too like distributor etc.

Take a look at the 1972 Mopar Parts Catalog page 9-01-0 Note 2 states "The 400 engine can be built with either a forged or cast crankshaft............"
Same pub shows the forged 400 crank P/N as 2268114...same as the 383 back to '62.

Sir, you are wrong about the crank in this case. The ind engines in MHs use the normal 6 bolt crank. If they were mounted on pumps or whatever it would be a 8 bolt extended crank. The dist is a normal unit. The water pump, heads, intake and exmanifolds are the funky 1s.
I had 1 in a 72 class A Winnie Indian..

You may be right about your MH only having 6 bolt flange but I would not consider a 413 motor home 413 an industrial 413.
If you want to see a 413 industrial , go to a some old scrap yard and find a CT800 or 900 heavy duty Dodge truck and then come back and tell me i'm wrong. Your dist. in your MH is probably the same or close to a normal dist. The dist in an industrial 413 CT 800 is different I can assure you. First it has a steel vacuum line that screws into the vac pot and it has a mechanical tach drive that makes the dist housing about about six inches high. The ind 413s that I owned in dump trucks had 8 bolt crank flanges.
The industrial 413 is governed and won't rev past 4000 or so rpm...........at least in the five CT800s that I had .
The heads are diff with angled plugs that were small thread style, water pump is hugh and engine was mounted under front pulley as opposed to side mounting .
Like I said go and fine a real 413 industrial and come back and tell me i'm wrong .

Industrial and MH 413s are really strange beasts. Anything can happen. Usually the ind engines had the extended crank flange.
Whatever you do, don't look at them like passenger car engines. Antything goes with those beasts.

You guys are right about the 413 truck motors. They dont look like your basic RB engine. My dad has a 66 CT800 with the 413. The distributor is not in the block. Its in the governor, which is in the same hole that the distributor should be in. So its huge as stated above. I was going to say too that I thought the crank hung out the back of the block more than the other RB's
