AVERAGE RATING OF 0

The Holley GM LS1/LS2/LS6 2x4V dual-plane was designed in the tradition of the great dual Holley 4160 induction systems that competed on drag strips, in Trans-Am and at Lemans in the 1960's.
The dual-plane equal-distribution layout produces great mid-range torque without compromising top end power. The LS engine architecture does not utilize an intake mounted water neck or distributor so it's perfect for two Holley carburetors

Appropriate for any street/performance, muscle car, or street rod enthusiast
