Holley 4 barrels and Carter Thermoquads have the same size air cleaner base. But some bases (like the ones I have) may interfere with a TQ accellerator pump arm and need to be cut, clearanced, spaced and/or dimpled. No problem with a Holley carb. I have an Amsoil assembly and a few K&N parts available.
Intakes and carb spacer are sold or pending.
