This high-rise single plane intake is capable of supporting up to 600 hp. The Victor jr. LS1 accepts a square bore carburetor & includes an electronic timing module that picks up map, crank position & cam position in order to drive the stock LS1 coil-on-plug ignition system. The module offers a choice of 6 built-in timing curves, each tailored for engine displacement, cam profiles & fuel grades. The #29087 (manifold only) can be used on LS2 applications when matched w/ MSD's #6012 LS2 ignition controller (available through MSD(R) performance).
