i have a sbc 383 that the outer ring on the balancer has come a apart at high rpm say around 6900.the rest of the balancer stayed on the motor and the motor was steal running before i shut it down.do you think there might be some interal damage?

I doubt it.
Pull the old one off and stick a new on there and go racing.

I've seen this happen before, all has been but there was 1 time I seen it cause a issue. Motor started to have a vibration after, if thats the case shut it off and pull it apart

I'd pull the filter, cut it open and check for any bearing material or metals. Just to be on the safe side. Won't take but a few minutes and $10.00 filter.

one more thing check the timing again. if you had a stock balancer the ring may have slipped alittle be fore it came off causing timing to be off. Let us know.

At 6900 rpm's ya might want to get an SFI approved balancer. JMO

Sprint cars run with NO BALANCER AT ALL...but their crank most likely cost a bit more than yours. :)

Yes Sir Rattler, as soon as I get some time in this car w/ the crazy frontend, I'm changing over to my HUB & WASHING MACHINE motor. Get some real use out of those zoomies on the car.

Don't buy a cheap one. It will do the same thing. Had a professional products one on my Pontiac. Thought something was wrong with my timing light. Was less than a year old.

the outer ring came loose from the hub. And this was on a 6000 rpm engine. Not like it turned higher to make it a piece of junk. It's not like it jsut slipped a few degrees, It came loose and you could reach down and spin it on the hub with one finger.
