Hello Guys, on my 1970 440 CID Chrysler engine, I have this harmonic balancer. Can anyone identify this harmonic balancer? I do not know if this is the correct balancer for my engine.
I have counterweights on my TC. Thanks in advance for any help

You do not have a 1970 engine. It is a cast crank motor. Newer than 1970.

Looks like a later cast crank balancer to me also. Maybe the crank was swapped in the engine? Might need to pull the pan and check the crank to see what you have.

Ok, this will be maybe a good teaching moment for me as well here...
Don't the cast crank balancers have something like "USE WITH CAST CRANK ONLY" or some such stamped
right into the inner part of the balancers like the OP's?
Further, are those really fat balancers also for cast cranks?
I think I have the same balancer as the OP:

This engine I have in Fred is a 1972 and I can't tell a cast crank from a forged one...
Can you tell what type of crank it is just from seeing the flange on the rear of it?

Sorry to hijack your thread Loka, but this is something I've asked a few times on here in the past
and it's the same question you're asking I think.
 
Looks like a 72 balancer 3614372. I think it was used with forged crank motors with 4 speeds. this is from 440 source: Shown above is damper #3512017, commonly known as a "six-pack" damper. This damper can be easily identified by a small .210" thousandths thick elliptical weight attached to the center hub. This version was used in '70 and '71 and has the offset pulley bolt pattern. Be careful not to confuse it with 3614372, which was used only in '72 and looks similar except for having a symmetrical pulley bolt pattern. The weight on the 3614372 may be slightly thicker at .255", but we have not been able to verify this.

Here's the link to all that:

I believe that damper was used on the 70 440-6 pack engines with the HD rods. 440'
 
Geez....if it's just an inch thick, I think it's a "six pack" (aka big rod 440) balancer. The cast crank ones are twice as thick

Any casting number visible on either side? Galen's White Book list's Damper applications from 62 - 75 if you can read the casting number.
 
That is a 70-71 440 HP balancer also known as a 6-pack balancer. That would be correct for a 70 440HP motor.

Ed yours is a forged crank 440 without the 6-pack rods. Different than what the OP has.
 
I pulled a 'virgin' 440 from an RV. '78 block. Stamped for cast crank, cast crank balancer, LY rods, and........it had a forged crank. Everything about the engine pointed to never being apart, right down to the bolts and gaskets. A few much more experienced Mopar motorheads agreed. It was kinda like an archaeological dig for car guys. Every measurement matched the original factory specs. So.....as we all know never say never when it comes to Chrysler Corp!

I'm with Purple and Ed. You can't really see it in the bottom pic but it said 'cast crankshaft only' or something like that.
The OP's looks like a 6-barrel balancer. I'm not arguing that point though as I could be wrong.

Here is that cast-crank balancer:

Were cast-crank balancers different on cars and RV's? I dunno...

Pictures of the pad stampings, and the casting numbers/dates would be great..

Yep, you can see it when blown up:

Thank you! Some of 'em were makin' me nervous up there... :)

By the way, is it possible to install a cast crank balancer onto a forged crank and/or vice versa?
 
Nice thread guys!
The 70 and 71 HP engines had the heavy 'sixpack' rods.
My 71 GTX engine was rebuilt in the States and had a stock damper fitted.
It had heavy rods and ugly bits welded on the crankshaft that look like they could fly off at any time!

So I found a good usable original sixpack damper and a specific B&M sixpack flexplate.
Then I lightened the rods down to 850 grams (610 bigend, 240 smallend) and rebalanced the crank.

The guy at the balancing shop said ''I didn't need the wiegthed damper and flexplate, as the rods were as light as LY rods''...:thumbsup:

The sixpack rod also known as the TRUCK rod was available until 1980!
All the UK Jensen Interceptor 440ci engines up until 1976 got the TRUCK rods.
They were steel crank and low compression 8.2 to one pistons.
They all used a standard damper no external weights as the cast piston was so light.
But they did make several 440ci sixpack Jensens in 1972 and 1973 as the performance was so grim!:cursin:
The earlier models with the 330hp 383 engines were in fact much quicker:thankyou:
