Last night started taking apart a 468 that I have had sitting in corner of shop for about a year.The engine had a external balance flexplate and a external balance damper on it.When I removed the pan,I found it had a forged steel crank that had various balance metal welded in some of the holes in the throws on the crank.I quess what Iam asking is can this engine still be a external balanced engine.Any response will be helpful.Thanks Nick

Yes. Even external balanced cranks can have the need for Mallory metal.

Thanks JMARK,The man that I got this engine from has passed away and I do remember him telling me that he thought it needed a new flexplate,but I dont remember why.The only thing I found on it was a couple of converter bolt holes were rough,no teeth on starter gear were bad,no cracks.I was thinking that the balance was different,might be the reason he told me this.Thanks Nick

I have had two 406's and one 454 balanced and both ended up with metal in the crank.
