Distributor Gear

I just purchased a Pertronix distributor for my new 350/330 hp GMPP crate engine.
The engine came with the stock HEI, but there is no room for the cap and I dont want to dent my firewall.
I understand that I need to use the melonized distributor gear, but what will happen if I use the stock steel gear on the pertronix?
The inside diameter of the HEI gear is smaller than the Pertronix gear...I guess I could have this machined to fit the Pertronix, but is there anyone who sells the correct diameter melonized gear for the Pertronix?

Re: Distributor Gear

Roller cams have to use a softer dizzy gear. There is no way around it.

Re: Distributor Gear

Unless GM (or you) has changed the 330hp crate engines to a roller cam, you do not need a melonized gear. All of the previous 330hp crate motors had hydraulic flat tappet cams in them.
