Iam also going all electric on my chevy V8.  I will have the Blue Mtn. =

    Is there any one out there who put a vacuum system
    on an auto conversion? I have a Chevy V8=20
    installed and would like some ideas on how other people
    attacked the Vacuum system. I thought of a electrical=20
    driven vacuum pump but do not know how much=20
    vacuum I need to pull. I bought a engine driven aircraft pump. But =
with it I need to find out what Rpm  it needs to be run at? Where it =
mount it ?And how I might install it.
    Or should I just give up on the vacuum system all to gerther
    and go all electrical.

    Thank you Wise ones
    Ron
