[old guys rule]

What is the best place to buy a harmonic balancer for a 440??

These fluid dampers can be installed regardless of type of crank balance? (internal/external)
Meaning to say, if your crank was balanced with the current installed damper (elastomer type) and you replace this with a fluid damper there is no risks involved in unbalance or so?
Currently i have a oem style damper but like to replace this with a fluid damper, just wondering the possibility's here.

Yes, you can replace a elastomer damper with a fluid damper although they will NOT work in a cast crank (external balance) application.

So an external balanced crank (cast) has a final balance done with all external component (flywheel, damper) to balance the full assembly.
An internal balanced crank (forged) is balanced as assembly without external components, and each attached external component is balanced on its own to maintain that crank balance?
Is that a way to describe it?
I am quite sure when balancing is done the mass and dimensions of components like flywheel and damper are included in the equation.
The 440's (my car is early '69 with '68 build date) have a forged crank which is internal balanced right?

Cast cranks with the cast crank external balancer & external TC weight are a "factory balance" not precision aftermarket quality balance. If you have the cast crank, and want an aftermarket balancer, you need the external balanced aftermarket version.

I would just get one of these, if you're not racing, from 440 Source and remove the weight for a forged crank.

Don't get the chrome one (ask me how I know). You'll have a terrible time seeing the marks.

Yeah i can understand having a hard time reading the numbers when checking timing.
Is there a separate weight installed on the 440 crank?
As far as i can see/know it is just the damper in place on mine.

A cast crank is externally balanced. Dampner and flywheel / torque converter have weights added.

The forged crank has been internally balanced by drilling holes in it. The dampner and flywheel / torque converter are neutrally balanced (no weights)

Lionized-- Thanx for the tip. Just ordered one. Dave
