Thanks Rick,

I do intend on taking it to a chassis dyno in a week or so. I finally found one near where I live. Just been trying to get it as ready as I can. the carb is a brand new Pro Systems. This is the setup it came with:

858 CFM
Mech Secondaries
Main Jets: Primary = 80 / Sec = 88
Acc Pumps: Pri = 50cc / Sec = 30cc
Squirters = 42 (both)
PV: Pri = 6.5 / Sec = Plug
Air Bleeds: Idle Air = 76 / Hi Air = 36
Float Level is < 50% in sight plug
The cam looks like it's black or dark burgandy color
Holes drilled in throttle plates
Secondary throttle plate is only very slightly open, almost closed at idle

MSD Digital 6 Plus ignition and MSD billet distributor
15 deg initial timing / 34 deg all in at 3,250 rpm

New Autolite 3924 plugs, gap = .045
New Ford Racing wires
100 octane premium gas
