    Default yet another cam question

    Ok guys, I usually have been running my headers dry but after a season of hard running, the coating is flaking off. I think it is because of getting the headers too hot. Anyway, Jet-hot is going to re coat them at no cost. Now my question is, can I run water to them with my cam?

    Cam specs;
    Advertised
    lift .660 IN, .620 EX
    duration
    298 in, 308 ex

    Gross lift
    .440 in, .414 ex

    Duration @ .050
    264 in, 270 ex

    Am I safe to run water inj. to my headers without issues?

    You have run more than 298/308 duration with wet headers and no problems. How much more?

    Exactly my thoughts but figured I'd ask the experts.

    NO.

    that cam on duration sounds HUGE for a 377 unless your turning it 7200 or 7400.

    Yeah Chris, this motor was intended for a drag car. I know the cam is a little big but untill I can afford to have you make me a new one. I'll run what I got...

    I'm running edelbrock performer rpm heads, with some port work done. 11.5-1 static compression. Currently spin a stainless "b" 5500. How much power am I leaving on the table?
