I.D. for crank dampners

[chgr500]

Is there any way to properly identify crank shaft dampners to the engine size.....I have a few loose NOS ones that I got with a parts lot some time back..I think one has a couple numbers on it the rest have nothing.....thanks for any input

There is a nice chart located on the 440 source website that has a lot of info on dampers.  It may just have the information you are looking for.

For big blocks there's only 3 kinds of balancers...Thin Steel, Thin HP steel ('70-'72 HP & 6-pack), & thick cast. All 3 look different and are NOT interchangable. Look in a Year One catalog for pics.
