Speedway Motors 91607112 Details

Our solid “big pieces in one box” kit is a LS upgrade bundle that covers the front accessory drive, top-end airflow, exhaust outlets, and the oiling foundation you need for an LS swap or performance refresh. At the center is the Speedway Motors LS serpentine front drive system with A/C, which includes the accessories, brackets, spacers, and hardware to get your belt drive handled with a clean, matched setup. 

Up top, it combines a high-RPM capable BTR Equalizer 1 cathedral-port intake manifold (designed for peak power in the 6,000–8,000 RPM range) with a 92mm, 4-bolt, drive-by-cable LS-style throttle body for strong airflow potential. For a finished look, you’re also getting smooth cast aluminum LS valve covers with coil mounts and a 2-piece design to help hide the coils, plus a 6061 aluminum Gen 4 timing cover kit with gasket/hardware to clean up the front of the engine. 

On the bottom side, the kit supports swap and turbo-friendly oiling with a low-profile rear-sump LS oil pan that includes a built-in AN-10 turbo oil drain, a 7-quart capacity, and internal baffling/trap doors for oil control. 

It rounds out the oiling package with the matching pickup tube, a one-piece steel/neoprene oil pan gasket, a billet/braided LS dipstick, and an AC Delco PF-61E oil filter (the pan is designed around the PF61 style filter). Exhaust is handled by cast iron LS swap manifolds with V-band outlets to simplify installation/removal and make fab and service easier.
