Yes, I am pretty sure that is what I ran after the bronze gear showed severe wear. Please, check with an engine shop to verify this. I would hate for something to happen if what I have relayed to you may not be 100% correct. Call Tyler Crockett at his shop. I was able to talk to him a couple of times, and he was a wealth of knowledge.

Just , please, double check my facts before you install and have a problem...

I always do... Thanks

j,
Are you sure you have the correct gear for your distributor ? It definitely should have some end play when it is installed. The distributor housing grows when it gets hot and will bind up the shaft if there is no play. Aluminum housings generally require more clearance than cast iron.

Also, a lot of distributor gears, bronze or otherwise, require you to drill a new hole to get the gear installed with the correct end play, look at the instructions that came with the gear and see what they say.

Last but not least, like others have already said, you really need to call the manufacturer of your particular camshaft and ask them which gear you should be running. In recent years there have been many changes in this area of the camshaft including pressed on gears, welded on gears etc. The only way to know for certain is to call the person that made your camshaft.

Hope this helps,

When we ran bronze gears with the Thunderbolt IV distributors, we generally had to take a few .001" off the top side of the bronze gear to get the pin thru the gear/shaft and keep the clearance right. On one distributor the bronze gear was bolt-on and on the other distributor the gear needed tweaking in the lathe. Consider taking all to an quality engine/machine shop, you shouldn't be there 15 minutes.
