Vacuum seconaries

[blingblingbob]

Does anyone know if you can modify the manifold pressure or something so that the vacuum secondaries don't open?

Higher speeds on long drives kill the fuel consumption as soon as I go over certain a speed.

Turbo it?

[blingblingbob]

That would require a conversion to EFI also

Nah I think he's talking about a carby setup not a B series P72 intake.

Just wire the secondaries shut.
