360 timing

Dynamic compression in the 9s AIN'T pump gas friendly. Also, camshafts do not "bleed off" cylinder pressure. That's not how it works. It all depends on when the intake valve closes. The later the intake valve closes, the later in the compression stroke the cylinder starts to build compression. To say the camshaft "bleeds off" pressure, insinuates that it is done at the end of the compression stroke, which is not true.
