On my new 383 with the Howards solid roller cam will I need to change the bottom gear on the dist. to a bronze one? If not will it chew up the cam or dist. gear? Pipe
If it is a billet cam you probably need a bronze gear. The distributor cam needs to be softer than the camshaft to protect the camshaft. Go with the cam manufacturer's recommendation.
or a "mellonized" (not sure about the spelling) gear; that's what I have in my roller cam set up; ate the stock distibutor gear up and stranding me; no one told me, but I guess I should have done my research ahead of time....
I run a mellonized gear on my SR cam. No issues with wear.
Make sure you check for proper alignment of the distributor gear and the cam gear if you have significantly changed the intake / heads. My MRII did not allow correct alignment with the AFR195CPs way back and chewed up two distributor gears on a HR cam (minor machine work and all was well). Food for thought.

I agree. A call or an email would provide some assurance.

Thanks for all the reply's. Where can I buy this mellonized gear at? The block was 0 decked has a set of Brodix Track 1 heads with a Mini Ram. I wonder if i'll have any issues? I might have to add some shims under the dist. to raise it some so it won't bottom out in the block. Pipe
