The FE`s normally had a different cam gear configuration than most aftermarket timing sets. Original OE installed cam gears were flat on the back (block side), and used a washer style spacer to control cam thrust movement. This spacer looked like a thick flat washer, with a slot in it, which allowed the camshaft dowel pin to fit into. Most aftermarket timing sets use a cam gear with a stepped section on the back, which fits inside the cams thrust plate, to control thrust. With this style of gear, the flat spacer MUST NOT be used, or it will cause the cam gear to stick out too far, and force the timing chain to work in a severe misalignment, as the cam and crank gears are supposed to be parallel to each other. Unfortunatley, some people are not aware of the differance in the cam gears, and also add the spacer. Is this possible in your case?
