Subject: REFLECTOR:V8 Vacuum system
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
