...they were custom - Saabnet.com Bulletin Board
The reason for the odd lobe shape on the intake was from recommendation from the camshaft grinder.
with staggered opening times and lifts, the effect on low end power and idle quality improves compared to two identical lobes due to swirl and other factors like plenum pressure changes so he says
the cams werent supposed to be tooo far over the factory redline (maybe 6500rpm peak), however once it goes back on the rollers ill find out where the power is made.
