    Motors'll hold up fine.
    Keep boost around 4 to 5 pounds.
    Keep RPM under 5000.

    Go with an intercooled centrifugal or whipple. They all offer good kits (whipple, procharger, vortech).
    I see London, I see France...

    If your looking for blowers I have a friend that has a complete set of b&M 250 efi blowers for sale that he used on his 36 outlaw. He took them off because he went to bigger cubic inch motors. He had them on 454 mag mpis and had good luck they just have to be set up correctly
