need to ID timing gears

have some NOS crank & cam timing gears, need to ID. I think the crank gear is for a Hi-Po 289, not sure about cam gear. Both gears are iron (not nylon jacket type)

C30Z-6306-A crank gear

C30Z-6256-C cam gear

thanks,

C30Z-6306-A crank gear

Hi-po application, 21 teeth

C30Z-6256-C cam gear

Not a hi-po application, 45 teeth, std. 289, the hi-po one is C3OZ-6256-A, 42 teeth and different thickness

thanks a million Charles. I'm listing some odds 'n ends for ebay auction and am trying to get the descriptions right.

If you run across the correct hi-po cam gear, I would be interested.

is the cam gear harder to locate than the crank timing gear ?
