[Shotimes] how to change cams?

[Jason Hartberger]

I was under the impression that swapping out MTX cams for the ATX cams 
(intake) would yield better power? The MTX cams give greater lift... so 
how would this not be a good upgrade? I'm genuinely curious... I mean, I 
didn't spend a whole lot on these cams so I'm not *too* worried, but I 
need to do a 60K anyway, I figured this would be a good excuse to get a 
*little* more power out of it... and don't worry, I won't be getting new 
tensioners.
