Outer Limits 4x4 Board

Is there an adaptor available for a squarebore 4 barrel holley to the two barrel TB42 manifold?

Thanks

There are universal ones you drill (they have the holley pattern), I'd suggest a 2bbl 500 cfm would be sufficient though.

They are time consuming to tune but the factory carby can be jetted to suit engine mods, we have used a 350 Holley in a blow through turbo application, Can't use vacuum secondaries on a blow through.
