Description
If you’re running a modern 4-barrel carburetor on a classic engine or swapping carb styles, manifold compatibility becomes your biggest headache. This Mr. Gasket adapter eliminates that problem by converting your square-bore intake to accept spread-bore carburetors—or vice versa—without fabrication or manifold replacement. It’s a straightforward bolt-on solution that saves you hundreds in machine work while maintaining clean, reliable fuel delivery.
The adapter ships complete with gaskets, studs, nuts, and washers, so you have everything needed for installation right out of the box. At 3/4-inch thick, it provides proper carburetor positioning and ensures a sealed interface between mismatched bore patterns.
