LS Conversion Specialists

LS engine swap kits for 1955 to 2003 cars and trucks

1964-1972 GM Trucks LS Conversion

This LS swap kit was specifically designed for 1964-1972 GM ½ ton 2 wheel drive trucks. It was designed around our GM LH8 and High Clearance Oil Pan kits. The engine mounts kit includes frame brackets that bolt into existing holes in the frame and the kit was designed to give you the best options for other components. 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.  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 Truck

No generic hope-it-fits parts here. Everything was developed on a real project truck 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 mid-length headers use a gasket-less ball and socket type collector for a leak free install. The long tubes feature a slip-fit collector that when used in conjunction with band clamps offer the best ground clearance in the industry. 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 support up to 500hp. For more power 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.

Exhaust Accessories
