I picked up a Summit Racing balancer recently. The overall height and diameter are good, but it's thinner then the one I took off. You see in the pick below. Anyone know if this will be a problem?
Might need to extend your timing tab/pointer forward a bit.
Do this Now ... scribe a line through centerline of hub outward to edge of outer ring ...
... that'll be your reference when periodically checking for outer ring-rubber slippage.
Also, verify piston at True TDC with a piston stop ... then verify the damper's mark agrees at zero/TDC ... relationship of keyway to mark varied over years.
FWIW ... me & nearly everybody ran about 4 1/2 lb early-type sbc dampers on regional circletrack 355 ... with light clutchpak ...
... my drivers could manage touchier accel-decel and resulting tendancy to wheelspin-hop when gassing up while still in a turn ...
... but, depending on application, lighter is not Always better. If it were, all cars would come OE with a two-pound piece.
Just out of curiosity, could you put both of them on a bathroom scale?
Sorry, I had it installed before I saw your post. They seemed similar in weight, just by lifting them, if that is useful at all.

I went ahead and installed it and everything looks like it'll be good. Thanks for the advice on the scribe line, that's a great idea.

Summit harmonic balancer is thinner than oem.
