Evaluate Timing chain sets
They would also be balanced just like a damper, converter, flywheel, or what ever spins, Even your factory rear axles with the hole to remove them has two smaller holes opposite to balance them after 67.
Having your cam and gear assembly with the eccentric attached balanced. That would tell you if your camshaft was balanced with the eccentric on it. If it was your timing gear/sprocket should be neutral balanced . Not all these race cams today consider the use of the oblong eccentric bolted to the front of the cam. Because the fuel pump was eliminated in 1988. 35 years ago.
Does it mean a lot if your street engine has a balance cam assembly? Who knows. But like I said before harmonics play hell on all rotating parts even your tires. Why would you see a reason for the holes on one side of this timing sprocket? I would say for balancing. And if the billet sprocket was that far out of balance on its own there would be an issue with material .
If my son gets freed up I'll see if I can get him to put this on the digital balancer for some numbers with a billet roller cam and a stock cam. With and without a eccentric.
I am also curious to see some numbers on this.
I would say everything must be balanced. Years ago at the beginning the LA had an nylon covered aluminum top gear. The balance for the eccentric would have been built into the camshaft as any turning engine part things need to be balanced. Today Good camshaft manufactures balance their cams. Sprockets/gears.
