1977-1990 B-Body LS Conversion Kit
This swap kit is for the 1977-1990 Caprice, Parisienne, LeSabre, Delta and other B-Body GM cars. It was designed around our LH8 oil pan kit. The frame brackets bolt into existing holes in the frame so you know the engine will have clearance for accessory drives, factory AC box, power brake booster, and aftermarket suspension components. Unlike others, our kit positions the engine so there is no steering interference and maintains the proper drive-line angle for smooth highway cruising. We offer a complete line of Muscle Rods headers that give unparalleled performance and ground clearance with sizes that are matched to your engine combo. These combined parts offer an easy, strong, and clean installation of your LS engine.
Includes the following:
Includes motor mounts, frame brackets, transmission crossmember, transmission mount, and hardware. Manufactured from the highest grade American made steel. They're laser cut, precision bent, powder coated and feature polyurethane bushings. It has a lifetime free replacement warranty on the bushings
The LH8 pan is the oil pan that our LS swap was designed around. It comes standard or machined for the oil bypass valve to use with displacement on demand or variable valve timing. Includes new full length windage tray, pickup tube, hardware, gasket and dipstick.
Optional headers are available - click the dropdown to add them to your cart, and get your B-Body on the road tomorrow! Please
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 engine combination. Our 1 ¾” mid-length headers offer great ground clearance and support up to 500hp. Our 1 ¾” long-tubes will support up to 600hp. 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.
This kit does not include headers. You can upgrade to headers based on your power goals, or come back to order them when you are further along. In either case, you cannot go wrong!
