    Got some flow numbers today!

    I'm in the process of building a bbc and just had the heads flow checked. The heads are Patriot Performance freedom series 320cc.

    lift----cfm(flow)
    .100-89.5
    .200-148.8
    .300-209.6
    .400-259.8
    .450-282.8
    .500-300.8
    .550-306.4
    .600-318.7
    .650-331.2
    .700-347.8

    This is out of the box untouched at 28in of water. They dont quite flow what they advertise but it was quite a bit better than the other brand they compared to. I dont wanna get into a pissin match I just wanted to share what info I learned today. 8)

    There going on my low budget 468 they should work well for it. 10.2 to 1 compression. Pump gas looking for a nice 11 second street car.
