    I've updated my blower. My Mooneyham had been maintained but wasn't ever restripped. It was very loose. At 25 over it would make 16-17#s max.
    My new Littlefield is nice & tight (brand new). On my old combo, about 10% over was 14#s. I'm thinking starting this blower at 1:1 or even a few under to get the feel of it.
    Is there a general consensus on how much a new blower pics up?
    Mathmatically, 1:1 should be 14psi or so (387" sbc)

    This is a 7.60 index car, blown alcohol FED.

    BOth are std helix.

    Littlefield is a competition blower, not an LB.

    Don't know what you mean by that. The LB22 Littlefield is their best competition blower.

    They have a series called "competition". It's not a retro (LB) it is a standard helix, cast case stripped 671
