i have a mopar purple shaft one bolt cam i bought the cam bolt but i dident have a washer with it does it require a washer for it before i install the cam bolt to the camshaft if so where do i find the correct washer for it. thank you.

I will tell you this , there is a pin on the camshaft,that pin must be covered by the washer,this very important because the pin can walk out of its position and then there is nothing to hold it to proper alignment with the gear/camshaft.

I had a moronic machine shop that assembled the engine before i could do a final inspection,well they put to small of a washer on the camshaft and yes that pin walked its way out until i was on the track and sure enough every thing shut down since the gear/timing chain were no longer on the engine, there was a quiet breeze at about 80 mph and i knew something was wrong, and yes it trashed 4 valves in the process and they were edlebrock valves special to the alloy heads, so make sure you have the RIGHT parts!

Yes, Randy a hardened washer with the flat side of the washer facing the camshaft drive and Locktite Red on the bolt. Torque to 35 ft. lbs.(this is important) If the bolt comes undone it will surely shear the timing pin right off. As Drew found out the hard way. Hemi's and 440SixPacks came with 3 bolt retention for this very purpose.

From memory it is a really thick washer as Drew says. More like a spacer than a washer.
