I have a gen 6 block, but switched to a thunderbolt iv ignition. My motor cam with a roller cam, but not sure what gear comes on the thunderbolt iv distributor.

Any ideas or suggestions appreciated.

Thanks

your cam is the two piece crane that uses the standard dist gear.

If you're going to replace the gear its a .491'' I.D.

So it doesn't take a special material. The factory gear is ok to use then.

Thanks

I guess you didn't believe me in your other thread

Sorry about that griff. I just looked at the link you posted and I have no recall of even posting that. My wife and I went out Friday night and didn't get home till early in the morning after a long night of partying and I guess more drinking then I thought because I woke up Saturday thinking "I wonder what distributor gear I need".

Sorry for the double post everyone.

lol!!!!
