has anyone ran a set of these spacers on a dual 4 tunnel ram?

i'm curious how to tune a setup with these and if they might build strong torque. mike

An independent runner manifold needs to have carbs where each venturi feeds only one cylinder--like most motorcycles, for instance.

Good luck buying two carbs where the primary and secondary throttles aren't staged, but instead open at the same rate. You'd have to have the secondary side built exactly the same as the primary, too.

You might be able to find carbs like that, but I bet they cost a fortune.
