What harmonic balancer to choose?

Can someone tell me which harmonic balancer i should choose? I think im getting vibrations from the damper so im going to replace it, what damper is oem for a -87 5,7l TPI? Or should i go for a "performance" model? My engine is very near stock, only headers and deleted AIR. I think the oem is 6,75 in. but im not sure...

,Thanks

Re: What harmonic balancer to choose?

The damper is a pretty simple part. First check that the outer ring is not moving or otherwise coming off of the damper. Second, check that you don't see any obvious cracks or deterioration in the rubber bonding between the inner and outer parts. If neither of those things seem to be an issue then the damper should be fine. If you do decide to get a new damper I'd recommend just getting a stock style one.
