Re: E303 roller cam/which distributor and gear?
OK, the first thing to understand is that factory style (factory, and aftermarket replacements like FMS, crane, trickflo etc) hydraulic roller cams are not made from steel. They are made from austempered ductile iron billet.Next, don't try and run a soft gear like bronze in an engine with a camshaft made from austempered ductile iron billet that sees street useage. It will wear very quickly. And when it wears it dumps filings through the engine. The factory gear is just fine for over 300,000 miles.If you need a replacement distributor, ask the seller if the gear is compatible with austempered ductile iron billet camshafts. If the seller doesn't know there are two options- walk away and buy a distributor from someone who knows what they are selling, or- fit a mallory alloy steel distributor drive gear. These are compatible with austempered ductile iron billet cams (and regular flat tappet cams as well).Good luck
