anyone familiar with the fm9 cam?
specs of it are 232/236 .585/.598
yes i tried the search, but did not find much
how is the idle? is the clearance ok with stock heads? my main worry is that the car is a daily driver and for now, i only have 3.42 gears on an m6, and im assumming the cam will like 4.10 gears much better, should I be ok with 3.42 for the time being (while i save up enough $$$ for a new rearend), or will the surging be a little too much?

i'm gonna be running tsp's 231/237 595/598 112 on stock 3.42's for a while, i'm in the same boat as you(savin up for a rear-end). she shouldn't be too unmanagable, just gotta keep her a little higher in the rpm range. clearence should be fine with stock heads. idle will be pretty nice on a 112 if you get her tuned in well.
