Cylinder 8 not firing

Depends, but yea. :D

I compression tested the motor and all were about the same, so I pulled the valve covers and hit it with a remote starter switch and the #8 exhaust rocker only only moved about 1/8 inch.
That answered that.

Well yeah I was referring to your comment. I know you finding a rounded off lobe was NOT some funny SHAT, no sir, not at all.
