I digitzed some photos of the billet rollmaster timing chain for you guys/girls to check out. First pic below shows The alignment on the oil slots is DEAD ON! Pics show my original camshaft gear lined up with the new rollmaster cam timing sprocket.

The next picture shows the TRW sprocket I removed from my 343 that has been in there since the mid 80's. Note the oiling hole in the back of the gear. Next to it is the Rollmaster sprocket. It is noticeably lighter thatn the TRW piece and the machining is much better. The rollmanster sprocket eliminates alignment problems with the cam hole by incorporating a machined recess rather than a hole or pocket on the back, I measured the width of the machined recess and it is exactly the same distance out as the "hole" in the TRW gear. The advantage is that the recess supplies 360 degree oil flow around the recess and into the machined slot on the inside diameter of the gear, very smart design! The torrington bearing speaks for itself!
