Holley 2BBL To SBC TBI Front Mount

The TRANS-DAPT Holley 2BBL To SBC TBI Front Mount (Part Number 2204) is a precision throttle body adapter engineered to facilitate fuel injection system conversions on small-block Chevrolet engines. This 1/4-inch thick steel adapter bridges the gap between traditional Holley two-barrel intake manifolds and modern throttle-body injection (TBI) front-mount configurations, enabling engine builders and restoration specialists to upgrade carburetor-equipped platforms with contemporary fuel delivery technology without extensive manifold replacement.

Constructed from durable steel, this adapter weighs 2.09 pounds and measures 7.25 by 8 inches in overall footprint, making it compact enough for tight engine bay installations. The kit ships complete with gaskets and mounting hardware, eliminating the need to source fasteners separately. The adapter's design maintains proper gasket sealing surfaces and ensures correct TBI injector spray patterns relative to the intake valve openings, critical factors for optimal combustion efficiency and emission compliance in converted vehicles.

This adapter addresses a specific technical challenge: swapping a carbureted small-block Chevy to fuel injection while preserving existing Holley intake manifold investments. Engine builders, hot rod restorers, and performance enthusiasts performing carburetor-to-TBI conversions will appreciate the straightforward bolt-on design that reduces fabrication time and eliminates custom manifold work. The TRANS-DAPT solution is particularly valuable for those updating vintage powerplants with improved drivability and cold-start characteristics that modern fuel injection provides.
