I bought a (then Comp Cams Hex-A Just cam timing set .the Hex a just #3108 appears in the Summit catalog as a Cloyes now.It mentions a bushing that is turned with an allen wrench. It also is shown as a new item.I bought my Comp Cams Hex-A Just cam timing set in 2001. It had no allen wrench rotated bushing.I haven't started the engine yet.I have only turned the engine over by hand with wrench . While prepairing to start while priming the
oil system I noticed that the rockers wern't moving.After testing and tear down I found that the cam dowl had sheard flush with the cam..When asked by my wife if this could happen again I have to say yes.What would you replace it with? For a car that is more fun to drive than work on .Hard to work on hard to get to.and a failure when operating would be the end.Some of the convesation started over on the FE forumn.It is an older 90 inch wheelbase EM 427 FEsideoiler ,2x4s and shell solid lifters,
