I have a motorhome with a 460, 1987. If I buy a camshaft shaft or a whatever you call it (LOL) adjuster, so that it is not running 5 degrees retarded, will it still pass the pollution test Thanks Geoff.?

It may or may not. They retard the timing of cam to allow for more exhuast overlap with incoming mixutre to reduce NOx and HC's
Thanks. Then I redo the timing AFTER I have my last pollution test? Geoff.
