Camshaft Thrust Plate

method as specified in a chrysler Australia tech bulletin for Hemi 265

I didn't bother with the screw. too much hassle. things have moved on since 1976.


I used a 3 bolt cam, machined a Nylon? big block cam button and stuck it in the end. just cut it down until you can just fit the cover, then a bit more so it just just touches. the cover has not cracked and its been in there 10 years.

aftermarket aluminium covers come with a bolt already fitted....

1 bolt cam used a retainer as per the style shown above on these motors...but after market and all before about 1977 cams are all 3 bolt.

presume you could apply the same to a slant if you so desired. both motors use similar set up for dizzy and oil pump drive. i.e cam set up is similar.
and rely on the slope of the lobes and the profile of the lifters to keep cam in place.
the aftermarket doesn't get this quite right.

the hemi 6 suffers stupendous cam walk when its done 50,000+ miles in a police car or taxi on original style sprockets and chain.... hence the factory bulletin
modern double roller chain not so much.

timing set with torrington flat bearing on back of sprocket is a nice addition Romac/Rollmaster used to be the place to get that.
