[Healeys] "M" camshaft

[Bob Spidell]

Usually, a cam 'upgrade' goes along with other mods, higher compression, 
headers, higher mixture delivery, timing curve change, etc. Michael 
confirms the M cam doesn't cause drivability issues, but I don't think 
you'd get much, if any, performance increase without the other mods. If 
you put a really radical cam in an engine, you could get drivability 
issues (it probably wouldn't idle very well, for one thing). Are you 
thinking of installing one with a mind to do the other mods later?
