Lately folks have been using the MSD cam and dist gears with success. I highly recommend taking off the timing set and inspecting the oiling pasages, aftermarket sets can have blocked or incorrectly placed oiling pasages. If that is the case even a good set of dist gears won't last too long. |

Here are some pics of 3 different sources of gears as to how different they can be. The first pic is an MSD on the left and an original on the right. The second pic is another original on the left and the MSD on the right pictured end to end. The last is another MSD on top and I believe a crown brand pictured end to end. Pretty big differences in the pitch of the teeth and depth at the root, Mix any of the non oem dist gears with an original cam gear and it's a roll of the dice how it will end up.

Thanks for the pictures, yes they certainly do vary alot. I got all my parts ordered yesterday. Got a new timing cover from Bulltear (old one is for sale if anyone feels that chip is inconsequential). Went with the Crown gear set and Felpro gasket/seal kit from Summit.
I could not justify paying $120 for the MSD gear set while the Crown set was $29, especially without hearing any real push for the MSDs. Even the Tech at Summit felt the Crowns would be fine. Got a bit of clean up to do on the front of the engine today and then I will try to look for any issues with the oiling passages. Then its a wait for parts to arrive - or more specifically the timing cover from Bulltear..... |

Crown is the top supplier of Jeep parts, so they SHOULD be good...

I bought a set of Crown gears so we'll see I guess. They look pretty well machined. They were coated with some type of cosmoline or something and the cam gear in particular needed to have all of the holes and slots cleaned out good. I could see someone forgetting to do this causing oil flow issues.

Some good reading here on what to look for in a timing cover: http://www.ifsja.org/forums/vb/showthread.php?p=1678711#post1678711

Good read, thanks for posting. Ordered some distributor shims today - although I'm still not sure how tight to set this thing. Once they get here and my new cover gets here I'll start seeing how things line up and look. I am guessing that there is no set amount of clearance between the dizzy shaft and the oil pump drive shaft? Basically as long as they don't bind any - plus a bit for good measure?
