Get late-model muscle of the popular Gen III and the classic look of dual-quad carbs. Designed for LS1, LS6, LM7 (5.3L), LR4 (4.8L), and LQ4 (6.0L) engines, the RPM Air-Gap LS1 Dual-Quad delivers outstanding performance from 1500 to 6500 rpm. Included with the #7518/#75184 is an electronic timing module that picks up MAP, crank position, and cam position in order to drive the stock LS1 Coil-on-Plug ignition system. The #75187 (intake manifold only) can be used on LS2 applications when matched with MSD's #6012 LS2 ignition controller (available through MSD Performance). Also available, complete carb and manifold kits on page 130. Carb center-to-center measurement is 6-7/16.
