A carburetor works by creating a pressure difference which draws fuel out of the float bowl and through the jets. With such a small engine drawing through a much larger carburetor intake there might not be enough pressure difference to draw any fuel into the engine.

So you'd really want to add a supercharger. :laugh:

Holley makes a 390 cfm double pumper that work perfectly out of the box. Couple that with a .290 lift cam and you are unbeatable!

They also make a 325cfm center carb for a 3x2 setup, mech secondaries.. honestly its the one i'd give the best chance to working- but even then that's way more carb then a predator would likely ever be able to use
