460 harmonic balancer questions....

Well, I'm trying to get my bottom end together so I can take it to the machinist to have the rotating assembly balanced. I've searched and searched and I'm having a hell of a time finding the right balancer for my application.

It's a '79 460 (externally balanced crank). I've found one that specifically states that it needs the balancing weight on the crank behind the balancer(Powerforce plus balancer). Well the guy I talked to that was selling it even said these were problematic and they've had issues with the rivets coming loose. He suggested a remec (I think) balancer but didn't know which one to suggest for my application. I've also found out that this balancer is spec'd for about 6k-10k rpm range. I thought I found something in this unit until I looked further.

Can anyone suggest a place to look or someone to talk to about a street performance balancer. I'm sure I could find a balancer that would work for me in the $400 range but I'm looking for something a bit more reasonable. My old one is original and the outer ring has moved so the timing marks are waaaayyy off. It would be pretty dumb to bring it to my machinist to have the rotating assembly balanced.

Any and all help/suggestions would be greatly appreciated. I'm sure there is a reasonably priced balancer that I can get, but I'll be hanged if I can find it!

Thanks guys,

Nick

Have you tried OEM? Since yours is externally balanced, finding one at your friendly neighborhood Fomoco dealer should be pretty easy.

yes, unfortunately I have. I tried two dealers and both said that they need me to give them the part number! <sigh> so I gave them the part # off the one I have and they told me it's the wrong one for that year. Well, I kinda knew that, I thought it was for a '75 460 and I turned out to be right. I any even they couldn't give me a part # for the one I need. I have no idea why. I didn't think it could be this hard to find a dang damper. It was the typical "what vehical is it in?", told them it was in a boat and they practically laughed. I have no friggin idea what it came out of. I gave them the block #'s and that didn't help them figure it out either. Maybe I just dealt with two morons.

I thought all 460's were internally balancedOr is it just the truck engines that are externally balanced?

Sounds like typical dealer talk!!! I bought a darn good one off e-bay and had it here in 2-3 days. I bought a Powerforce which is made by Professional Products(alot of them as a buy it now on e-bay) They work GREAT! One of your best buys! Good Luck!!
By the way as you already know 1979 and up are externally balanced.

I talked to the guy that sells them on ebay (the powerforce damper) and he was pretty helpful but he also said that the powerforce plus damper had problems with loosing rivets and it's not really a good damper for a "street" application. It's not designed to dampen well until after 6k rpm. Hell I dunno, I'm sure I'm just over analyzing it but just wanted to get something for my application and bolt it on and be done with it. I really don't want the guesswork, especially since I'm having it all brought into my machinist. I'll do some more research on it tomorrow if I have time. I really appreciate the replies guys. Thanks!

Oh, and I already talked to the guy at flatlander and he wasn't sure either.

FYI, the balancers as I understand it are all the same. The difference is the 'hatchet' counter weight space the 79 and up BBF's use (similar to the 428 CJ/SCJ hatchets) for the external balance.

I think I'm all over that one that ford sells on the oem site. Thanks guys for the help I really do appreciate it. After all is said and done tho, I'm not sure if there is a difference in the balancers other than a 3 bolt for pulley 4bolt .....or there are aftermarket ones especially made for double keyed cranks and such. I THINK the stock replacement ones are the same as far as fitment goes (which is probably why no one could really tell me the difference or find one). This is my best guess at this point, but you can bet I'll find out for sure before it's done. Thanks again guys.

I talked to a Ford Racing tech today and he told me that the balancers are the same with a few exceptions. He said the only difference was the counter weight on external and the spacer for internal. There were also some differences in the depth of some of the balancers which would move the pulley in or out. Since this is going in a jet boat with only 1 pulley for the alternator, it appears I have no worries as far as fitment goes. It looks as tho I guessed right as did many people here. Thanks again guys. More dumb questions coming soon.
