Right now I have the Buddy Club Spec V cam which is 312 deg with 12.8mm lift on the intake and 306 with 11.8mm lift on the exhaust. I haven't ran the motor yet and am just curious on how it will run. I have gotten many different opinions on using this cam, some people say its not a good idea since it is intended for an all motor cam and that high lift under that much pressure is asking for something to go wrong. isn't high lift with longer duration to be good because it would give more time for air to fill the cylinders? and can't overlap help with turbo lag?

my hp goals are 350-400whp on pump gas. and 550ish on the track.
It is a AEBS sleeved b18b overbored to 84mm with a b16a head with full buddy club valvetrain (everything buddy club makes for the head is on there. from valves, retainers to cam gears.)
pauter rods with ross racing pistons.
type r bearings

What do you guys/gals think of that cam for that setup? Should I get a milder cam and y?
