I have a 1985, 351W out of a F-150 pick-up I am rebuilding, I am going to have the rotating assembly balanced, the harmonic balancer E4TE-B3A is kinda ratty looking so I am planning on replacing it I believe it is an external balance and it has 4 bolts can any one tell me if it is 28oz. or 50oz. I've Googled it but cant find how many ounces, I've also looked it up on Jegs and Summit just want to make sure I get the right one. would appreciate any help. Thanks

 

All 351W engines were 28.2 oz-in. imbalance.

 

Thank You, Beanscoot

 

You're welcome.

I also checked Google, and could not find conclusive evidence about that casting number, but it seemed to mostly turn up on 351 engines. And, as said previously, all 351Ws are 28.2 oz in unbalance.

By the way, dampers are acceptable even if the rubber is a bit cracked on the outside.

 

Thanks again, maybe I should just not worry about it,it is cracked a little on the rubber Im getting so much invested in engine parts I keep thinking just one more thing.
