Tuning a Proform/Holley carb, what parts and tools?

Ok, so maybe we are back to the pump?
Or I need a larger N/S?


On the last note, I borrowed a Ryobi laser temp gun tonight. It was already dark and cooler, plus I took these temps immediately on shutdown after pulling in the garage with the engine off. I need to test again in the afternoon with the engine running after beating on it. Any way here is what I got... All temps are °F

Fuel pump - 159
Line in - 110
Line out at filter - 140
Fuel Standoff into bowls - 161/149 f/r
Regulator -119
Carb main body - 112
Carb bowls - 120/114 f/r
Intake - 147
Heads - 178
Headers - 262
Coil - 142
Valve covers - 153
MSD 6AL - 135
Inner fenders - 132/137


Was thinking coil might be overheating.
Car ran good until 3200 in third gear and fell flat on it's face.If I let up, it comes back. I tightened the screws on the fuel bowls per Proform instructions and I did not see so many bubbles after. Both windows look about the same at 3k in park.
Lowered floats with fuel a little under center and tried again with no improvement.
Pulled limiter pill from MSD with no change.
When I get time I am thinking of plugging factory ignition back up rule out the MSD. Just can't seem to nail it down to fuel or ignition.
