Inliners International Forums General Discussion Engines Possible to reuse crankshaft timing gear

I am replacing the cam in a Chevy 250.I order another timing gear set.

Being curious ,I check the part numbers stamped on the new gears,to the gears on the 250 engine.Both sets had the same part numbers.Except the new gear set had three added numbers.About three inches from the part numbers.

There is only 3500 miles on the crank timing gear.

Would you use the use crankshaft timing gear with the new camshaft timing gear?
