1971-76 B-Body Impala

Everything here is made specifically for your car

No generic hope-it-fits parts here. Everything was developed on a real project car for the best possible fit.

1971-1976 B-Body LS Conversion

This LS swap kit is made specifically for 1971-1976 Impala and GM B-bodies. It was designed around our LH8 and High Clearance Oil Pan kits. The frame brackets bolt into existing holes in the frame and was designed to give you the best options for other components. Unlike most LS swap parts on the market this kit replaces the frame brackets in addition to the mounts, so you'll have clean mounting of your engine and not a mix of unrelated parts. Unlike other mounts, ours position the engine so there is no steering interference, and our crossmember maintains the proper drive-line angle for smooth highway cruising. It provides clearance for the factory heater box, power brake booster, and aftermarket suspension components. The following combined parts offer an easy, strong, and clean installation of your LS engine.

BRP Oil Pump Pickup Tube Girdle

Original GM oil pickup tubes are fastened to the pump with a single bolt mating flange on the tube. The bolt hole on the other side is not used. Our Girdle is cnc machined aluminum and goes over the original mating flange, wraps around the tube, and fastens using both bolt holes. Use with a little Locktight and it’s cheap insurance against an engine meltdown. It comes with two longer bolts for install.

Muscle Rods Headers

These are not your average swap headers. These headers offer many feature that are normally only on custom race headers. We start with 3/8" laser cut flanges with the tubes welded inside and out and then machined. They use a gasket-less ball and socket type collector for a leak free install. They're ceramic coated inside and out to fight performance robbing underhood temperatures then polished for a long lasting show quality finish. They have 1 ¾” primaries that support over 500 hp and offer great ground clearance with their mid-length. They include gaskets, bolts, reducers, and O2 sensor bungs.
