It depends on what the cam gear is made of. It has almost nothing to do with the type of cam or material of the cam. But fyi, roller cams are harder material that flat tappets.
Why does the gear need to be replaced?

Billy that's the one I was going to use.
Sorry no pics. Its currently installed and timed in the engine. Its nothing excessive looking they dont look like saw teeth or anything alarming. The lower bushing on the dizzy also seems out of tolerance as far as play is concerned now that Im thinking back to last time it was out.
The whole mess probably realistically has 80,000 miles on it minus the cap, rotor, and weight assembly.
Maybe I'll just replace the whole thing
but with a steel gear. That's what Comp and MSD Recommend. It just seemed initially concerning I wanted to make sure some n0ob wasn't just trying to sell me something and not realizing the potential amount of "pain in the ***" an incorrect gear could cause.

I have this same exact cam in my 302. Definitely do not use a bronze gear unless you want to be stranded on the side of the road in about 4500 miles (happened to me). The cam isn't billet steel, it's "austempered ductile iron" so you can use the stock OEM steel distributor gear no problem. Comp cams confirms this on their website and in this video they made:

Ah yes I remember this video....Wasn't much help because the cam was in the car by the time I figured out this could be an issue.
They said the biggest challenge is figuring out the cam's alloy....hit it with a wrench they say. My initial reaction...Or you could list it on your web site with the cam specs...GAHHH.
But hey if you say its ductile iron then that solves a lot of problems....The description seems to match what I remember seeing too!
Very helpful
Thank you!
