Ford 460 distributor gear shear
I just finished building a brand new 460 for my motorhome, added a mild Comp Cam w/ lifts, rocks, etc. This is 1989/90 TBI. I took it for a 50 mile test drive and shear'd 4 teeth on the distributor gear... had to get a two. What the heck?
I bought a new aftermarket rebuilt distributor and plan to stick it in. Comp Cam claims the stock distributor gears should work just fine with this cam.
I don't want to shear another or get another tow.
Any ideas why this happened? What next?
