    Z06 cam mod.

    I have a 99 T/A and have recently installed a Z06 cam and modified the rockers to roller rockers. I also have the 160 thermostat and Granatelli MAF sensor.
    Does anyone know how much of a gain in hp this would be?

    When I did my LS6 cam on my previous Camaro, I picked up 16 RWHP untuned. You didn't mention anything about tuning so I assume you haven't had tuning either. You probably gained around 10 from the rockers and nothing from the thermostat and MAF. I would guess you gained around 25 RWHP, untuned.
