Default Engine vibration question
Lately, I've been noticing a vibration in the engine right at 1700 RPM. Under 1600 RPM, it goes away. Over 1800 RPM, it goes away. Vibrates the car right at 1700 though.

Short block was built by a professional shop and balanced. Crank is stock, rods are preped stock, pistons are KB. Balancer is SFI from FMS, flywheel is billet steel also from FMS. Clutch is a Centerforce unit.

If there was an out of balance condition in the engine, the vibration would get worse as the RPM went up. Thoughts? Suggestions? Anything to worry about?
