<VV> Single Carburetor

[Mike McCrae]

Please read my article on using the single mounted four barrel carb in Corsa, The hesitation is from carb ice and the too large venturi found on the 350 or 500 Holley.
Do NOT use ported vacuum, but draw directly from manifold vacuum. the 390 four barrel has smaller primaries, so a stronger signal is sent to the carb. The plenum MUST be heated to 
eliminate carb ice and fuel/air condensation on the walls of the runners...
