Hooked up a wide band sensor and A/F meter and went for a quick fang last night... here are the results:
Idle mixture is in the 12.2 to 13.2 range.
This chart is cruising averages, i.e just opening the primary's.
This chart is WOT. I know it will make power to 7500 but I limited it to 6500 until i'm about 70% complete with a new stroker bottom end. The current bottom end is the one that came with the car, and apart from a new oil pump, and 8lt sump, all is standard i.e cast pistons/standard rod + bolts etc.
351C + AFD4v + TFC + 30deg locked out advance
Carby specs (Proform 750DP):
Pri Jet: #71 (#74 from factory)
Sec Jet: #80 W/Jet Extensions (#84 from factory)
P.V. Pri: #45
P.V. Sec: Plugged
Pri Nozzle: #31
Sec Nozzle: #31
Acc Pump: 30cc Pri & Sec
Pump Cam: Pink Pri and Sec, position #1
Idle Air Bleeds: .075" Pri. .073" Sec. 10-32 Screw-in Type
High Speed Bleeds: .036" 10-32 Screw-in Type
Floats: Brass Primary, Nitrophyl Secondary (notched for jet ext)
Adjustable secondary air flow bracket
.110" needle and seat assemblies
Any carby/tuning gurus out there? Any tips would be much appreciated.
I'm going to downsize the pri and sec jets to #70 and #78 respectively, and go for another run this week, will post results.
