1991-96 B-Body LS Conversion

This LS swap kit is for the 1991-1996 Impala SS, Caprice, and Road Master, including station wagons. It was designed around our LH8 and High Clearance Oil Pan kits. The frame brackets bolt into existing holes in the frame and it 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 AC box, power brake booster, and aftermarket suspension components. We offer a complete line of Muscle Rods headers with a unique design that gives great ground clearance, with sizes to match your horsepower level. The following combined parts offer an easy, strong, and clean installation of your LS engine. See our installation guide for more info on this LS swap.

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.

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. The long tube headers feature bolt-on race inspired collectors for ease of installation and tuning of primary length. The mid-lengths 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.

We offer several sizes of headers so you can match them to your horsepower level. Our 1¾” mid-length headers offer great ground clearance and support up to 500hp. For more than 600hp we offer 1 7/8” long-tubes, and for big cubic inch monster engines our 2" is a perfect match. Our stepped headers offer great high rpm performance while retaining good low and mid-range power. They all include gaskets, bolts, reducers, and O2 sensor bungs.
