Evening all,

Just been having a little think about the next engine build while I'm away for work and does anyone know the differences (if any) in the profiles of the AAZ and ABL camshafts? I was under the impression that the pump was the only difference on the two engines (the one on the AAZ bringing it up to 75bhp - do stand to be corrected though). I know they both share the crank pulley issue!

I'm thinking of toying with a few cams in the AHU head (or maybe I should quit messing and go straight to a fancy stage 2).
