Default New 383 eating distributor gear!!!!

SO 89 l98 383 with lpe 219 cam just pulled the dist and noticed some wear on one side of the dist gear. Checked runout on the shaft and found it to be .08 in (the runout is right at the wear point)

So whats a good affordable replacement or can i get away with just swapping out the shaft ( i have an old one floating around that i will check for straightness.

O and im pretty sure the shaft was bent from a massive backfire from before the engine was rebuilt. (no really this **** backfired so hard i had to replace all my exhaust gaskets)

Does the material the dist gear is made of match that required by the cam ?

I believe the Lingenfelter 219 requires a melonized gear to be used... You could always get a composite gear which will work with any cam material ,plus they never wear out....WW

+1 - The gear you have probably doesn't match the cam selected.

Im getting a new Gm Melonized to go back in with the new distributor but it died due to a bent shaft. the runout is .08 or .1 in now if i put some tape over the toothed part and pull the runout there its smooth with almost no runout. Therefore the cam ate the bent part out. (why the gear was only half eaten) So I just need to know what a good replacement distributor.

Is your cam gear billet or a pressed on iron gear?

In that case, you should be able to use an iron (stock) gear. The runout must be heating you distributor gear. Hopefully the cam is ok.

Here is an iron distributor gear that will mesh with your iron cam gear...Here's what the details say..... "Iron gears are designed for iron camshafts or roller cams with existing iron gears".............I have a pressed on iron gear also, and this is the dizzy gear Im using....WW

dist gear with no problems at all over this years. I didn't want to change it.
