[Healeys] "M" camshaft

[S and T Miller]

I was wondering what driving/ idle characteristics would be like if a "M" camshaft was installed in a otherwise stock engine/ carb setup? I lack knowledge of camshaft degrees, duration, and all those technical details concerning camshafts, but I'm interested in drivers seat impressions.  Seems "M" camshaft are more readily available at the moment and for a much more reasonable price.

And to take it a step further,  what about a "M" camshaft and "M" pistons with stock carb setup? Obviously driving the car prior to sourcing the "M" carbs/intake.  Just curious.
Thank you,  Shawn
