  • 1970-1981 F-Body LS Conversion Kit

This swap kit is for the 1970-1981 Camaro and Firebird. It was designed around our f-body oil pan using our Sure-Fit crossmember system. It bolts into existing holes in the subframe and was designed to give you the most options for front accessory drives. 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 parts that are weak and don't work together properly. Unlike others, our kit positions the engine so there is no steering interference and 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 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.

1970-1981 F-Body LS Conversion Kit

This swap kit is for the 1970-1981 Camaro and Firebird. It was designed around our f-body oil pan using our Sure-Fit crossmember system. It bolts into existing holes in the subframe and was designed to give you the most options for front accessory drives. 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 parts that are weak and don't work together properly. Unlike others, our kit positions the engine so there is no steering interference and 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 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.

 

This kit includes the following:

Mount and Crossmember Kit

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.  Comes with a lifetime free replacement warranty on the bushings.

F-body Oil Pan kit

The oil pan our kit was designed around. Comes standard or machined for the oil bypass valve for use with displacement on demand or variable valve timing. Includes new full length windage tray, pickup tube, hardware, gasket, dipstick, and our pickup tube girdle.

 Oil Pump Pickup Tube Girdle

Original GM oil pickup tubes are fastened to the pump with only one bolt with a tear drop shaped mating flange on the tube. There is another threaded bolt hole on the other side that 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 bolt for install.

Optional LS Swap Headers (Pick Your Power Level)

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!

Special Note

Measure your subframe

Since late subframes can be used in early cars with simple modifications it is important to measure yours. The center of the rear body mount to the back crossmember mounting hole. 1970-74 subframes are roughly 7” while 1975-81 subframes are 10” or more.
