Wow, I think I'm reaching the end of my tolerance.

Motor is a '98 Vortec Gen6. I received it in '99, don't remember the person's name. The balancer that is on it always has looked weird, but I've gone forward. I swear it looked like it had NEVER been removed, and absolute factory stock.

The motor never came with a front pulley drive ... so I got the part number for a serpentine crank pulley. Received it, the pulley looks like what I would expect.

Now the problem ... the balancer has a "hub" cast into it. This hub has 6 threaded holes, and moves the position out ~1.5" from what a normal balancer face would look like. And, the holes centerline will not line up with a '69 396 crank pulley, or my new serpentine crank pulley.

Has anyone ever seen a balancer with a hub sticking out the front of it. Is it possible somebody switched them? How would I find an appropriate balancer?

Tonight I'll try taking pictures, since that's about the best way to describe ... but anyone have any help?

Thanks, Neal

Any help??

That is a big truck gen 6 motor I have seen those before and before you ask it is a shortdeck block. If lucky it might be one of the steel crank gen 6 motor. You will need a balancer for regular truck like a c 3500 with a 454. Please post the block casting numbers.

Casting is:
10237297...454.......96-up...4-bolt, Vortec 7400", "L-29" Gen.VI

I guess a "big truck" balancer would explain why it fits the crank properly. I've just never seen one with a hub on it like that. I was looking around car-parts.com and looks like quite a few advertised ~$50 range. Sucks ... could've saved the money I spent on the crank pulley probably that way.

Thanks, Neal

My truck 427 uses a balancer just like that so just get a balancer for your regular every day light duty truck. The replacement balancer needs to come from a 1996 - 2000 vortec 454 vin code j vechicle.
