Hi Earle,
Partial throttle opening is Holley's advantage, it comes alive with
it's stock 8.5 inches of mercury, or what I use opens the diaphragm
power valve at 10.5: http://www.----------.com/holley2.jpg And yes we
should choose the cubic feet per minute, for the RPM range we're
probably going to use, and I use the 850 on my 462" Thunderbird, and
400" Real Jeep. This style of Holley looks just like that Ford used in
'57 at 450 CFMs to the 1200 CFM Dominator pictured in the previous post.
