Does it fit my engine?

The Holley GM 2x4 dual plane manifold is designed in the tradition of the great dual Holley 4160 induction systems that competed on drag strips, in Trans-Am at Lemans in the 1960's. The technology of the LS pushrod engine is now mated with the impressive multi-carb looks and performance of the muscle car era!

Fits all GM LS Gen III or Gen IV engines equipped with LS3/L92 style rectangular port cylinder heads.
Dual plane design for equal distribution and great mid-range torque without comprimising top-end power
Perfect for any street/performance, muscle car or street rod enthusiast
Cast aluminum construction, Black Ceramic Coated
Power band from 1500-7000rpm
