Does anyone have an aftermarket cam with roller rockers on a 3.4L? Or is anyone running nitrous? If so what are the gains and what shot are you running?

 

without porting the heads, a bigger cam wont do much.
a mild port job (and lower intake opened up) and a 260-270 adv. duration cam will wake the lil motor up pretty good (+45-55 hp with good intake and exhaust,but thats a dyno 2000 based guesstamite)

 

Got both.

Well all 3, cam, roller rockers and port and polish.

 

^ also has a car that hasnt ever ran

 

Me japan, car Newport Maine?
That equals lots of distance.
My car has been through 2 engines and has not run sence I joined the Air force in 2002.
The Z28 runs great and will stomp 3.4L's any time.
