Camshaft sprocket thrust surface keeps cam from moving into the block and thrust plate keeps cam shaft from moving out of the block. A very simple, but effective arrangement! It looks like I have about 25 to 30 mil clearance between rear plug and end of the camshaft. I'll have to double check tomorrow.

This morning, full of energy I put the question of rear cam plug to cam clearance to bed.

Dial gauge was set up to monitor camshaft end play movement.

Cam was pushed until rear cam flange came in contact with rear plug (not good). Dial reads 35mil


Cam was pulled forward until thrust plate stop further movement. Dial reads 81mil


Installed cam gear and measure. Dial reads 76 mil


Well I have 41 mills of clearance - that should be enough. If not I'll find out the hard way!
