This can also allow for a denser fuel mixure to help increase performance in some applications, as well as provide additional plenum volume. 4-hole design fits Holley 4150/4160 4-barrel carbs as well as most Carter and Edelbrock models with a squarebore design. Gasket, studs, washers and nuts are included.
