  • Cam help

    I was curious if my dyno numbers were a bit less then what they should be? I have a 95 z with afr heads, 2.02/1.6. I have TPIS zz-409 cam (duration at.5 is 226/226, lift with the 1.6 rockers is .554/.554, with 112 Lobe sep) I run full length headers with exhaust dumps. It's bored .040 to 358 and a forged bottom end. Alos the springs habe been upgraded to handle a .600 lift52mm t.b I went to two dynos and my results were...
    328rwhp x 1.25=410
    and the other dyno...
    355rwhp x 1.18=418.9

    My question is shouldn't I be putting alot more down than this???? Other guys with LT1's are putting 380-430 rwhp. Any suggestions on other cams??? I also run a direct nitrous kit (150 shot)
    I was thinking about TPIS' s cam (zz-x) those specs are duration @.5 290/290 and lift is .558/.558 with 1.5 rockers with a 112lsa
    is it worth the time and money? h.p gains???

    please help, I'd really appreciate it!!

    Do you have the head flow info on the heads? Which AFR heads are they? What other mods are done? Drivetrain? Was the car tuned after the h/c install?
