451Mopar,
Thanks for the link!

madscientist,
Are you also speaking of Line boring a BB Chrysler cam bearing bores? As I stated above other machine shops have stated this isnt possible.

I'm not a machinist and not saying anyone is right or wrong, but I attempted to have local machine shops perform this repair including Mopar specialized machine shops and everyone said they either cant do it because the bores are stepped and/or they dont have the proper equipment.

I did try to call and Email Muscle Motors last week but I haven't heard back from them yet. Hence, my reasoning to try and take on the project myself. The article makes it look rather simple as long as you take your time and "measure twice and cut once"

Thanks to all!



The biggest issue is getting oversized bearings. I believe the shop I used to work at has purchased a line bore that will do the job. Just getting bearings. I have to go to town in a couple of weeks and I'll stop by and see. I know he has the tooling to do roller cam bearings. So I can't see why you couldn't line bore a BBM if you can find the bearings.
