HOLLEY CARBURETOR FLANGE GASKET 8BP-1538 FOR HOLLEY 4150 & 4160 4 BARREL

Holley part number 8BP-1538 represents a vintage “Track Pak” carburetor flange base gasket. Because this is a legacy part number, it has generally been superseded by universal replacements. For a 4-barrel square-bore Holley carburetor (such as the 4150 or 4160), you can use this standard open-center gasket. For standard 4150/4160 square-bore carburetors, a 4-hole or open-center composite gasket creates a crucial seal against vacuum leaks.
