Sorry to keep beating a dead horse but can someone give me the actual dimensions of a cam bolt washer for an FE---I bought the largest washer ARP lists in 7/16 and it does not even touch the cam dowel--I saw where a sbc washer would work and tried to look up one of those on summit to no avail? My last bolt and washer I had is under a sealed up timing cover so I cant see it---Every ad I see for a bolt and washer kit gives no dimension info--I am spending 2 weeks trying to find a 2.00 piece!!!
We use a cam washer like Barry's except I drill a small recess where the washer goes on cam aligning pin. The pin
I use sticks out into the recess.This with two pins guarantees that the bolt won't back off. I have had a timing chain break so I am anal about seeing this does not happen again. When the cam quits turning at high RPM, you can kiss the entire valve train good bye.
