is there any factory cam used in the M103 engine that is better for power than others? I currently have three to chose from, my original and those on the rebuilt heads on the bench (not there to pull the numbers at the moment). I'm aware that the manual trans cars had slightly different timing on the intakes. Or, alternatively, would the power difference be so small as not to be noticed? My stock USA 1987 300E (without factory EGR) runs rather well, but while its apart... Thanks!
