" PS: Don't forget AMC/Jeep changed the timing of the cam through the chain 
" and gears. (maybe the crank gear was installed backwards for more advanced 
" cam timing?) When I did the 3 keyway setup on my '66 Fairlane's 289, I tried 
" the advanced spot and got great rubber burning with major ping and the power 
" band died at 2,500 RPM!

advancing and retarding the cam are standard racer ways of moving the
powerband down or up the rpm range, and likewise an indicator of
whether you'd run better with a smaller or larger cam.

i recall hearing that when they were active in scca showroom stock,
the amc racers retarded the late '70s 2bbl cam 13*.
