I have a 95 z with a six speed tranny. I have afr 190cc heads and 1.6 rockers. My concern is, that my power should not be falling off below six grand like it is. It is not a dramatic drop(no vavle float) but I think that it should be making power at atleast 6300rpm. Does anyone have a similar setyp(H/C) or suggestions?(someone to tune it)My air-to-fuel is where it shoud be.
Thanks for your help guys
Also, the specs for that particular cam are :ZZ-409 Hyd Roller:

Adv. duration 287/287, duration @.050 226/226, Lift .520/.520. 112 LSA.

*Those specs are with the stock 1.5 rockers

What are the flow numbers for those heads? Single pattern is not exactly normal for a smallblock Chevy.

I ran one YEARS ago. It was with a blower for the most part but even at 9.2 CR it would pull to 6,200 any time I wanted

the ZZ9 makes power to 6000+ with the right heads. your heads should support this and the 409 is supposed to be a stronger cam. i would think you should be making power to 6300 also. id maybe see about having someone dyno tune the engine. there could be more power there. you say the AFR is where is should be, but what about spark? true more spark could lean it out, but it may not. also your car may like more fuel and more spark, would could give the same AFR as less fuel and less spark. the point is every cars different, if you havent had it dyno tuned, do so. what about your fuel pump? are you sure your pressure isnt falling off? just a thought. i think theres more there possibly, only one way to find out.

I've upgraded my fuel pump, and i had the dyno tuner stabilizw my fuel trims, so they are right where they need to be. Anyone have dyno numbers from this cam?

Well with 14Psi of boost I have recorded run from about 5mph to over 160mph and back to zero in under a mile...as testified to by the washington state patrol

I was shifting at 6,200 and lifted around 6,100 in 4th

TwoFast4Lv,

Is the ZZ409 cam a good cam for a forced induction motor? It obviously ran good in your car but I am new to cam specs and still pretty ignorant about cam selection. I have heard though that cams for forced induction cars should be 114LSA or greater. Do you have any input?

Well, I know you asked the other guy, but look at my sig and the results with a 112 lobe sep, and 226/226 duration

I would use the cam again with Boost yes. This one was cut on Large lobe seperation(115*) I might get them to add a few degree's on the exhaust like 236*
