Comp Cams 2121 double roller timing chain set.

Anyone using it w/ the stock fuel pump eccentric? How long? Any noise/problems? It does not have the machined surface for the eccentric and the outer ring seems loose. Any help greatly appreciated, it is holding up my whole build.

New gear from comp :




Old gear from 4,000 mile timing set that was on the truck, outer eccentric ring is just as loose on it, but it has a machined surface for the eccentric :

The outer ring is supposed to be loose. There is enough for it to seat to. Always use plenty of red Loctite on the bolt and torque it to 50 foot pounds.

what mark said! good to go.

Little thrust is good. once the fuel pump arm puts pressure on it you'll never know!
