1970-72 Monte Carlo LS Conversion

This LS swap kit is made specifically for 1970-72 Monte Carlo. It was designed around High Clearance Oil Pan kit. 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 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 car

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

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.

EFI In-Tank Pump Fuel Tanks kits

These conversion fuel tanks solve the problem of supplying your new LS engine with a steady flow of fuel. The tanks, made specifically for your car, feature a recessed area in the top for the fuel pump module and sending unit, so no floor modifications are needed for clearance. They have an innovative baffling system inside to control fuel slosh and keep the pump fed even at low fuel levels and extreme driving conditions. They are galvanized steel and powder coated silver for maximum durability. The kit includes a fuel sending unit designed to work with your factory style fuel gauge. The included fuel pump module features an in-tank wiring harness and three ports - one for the feed line, one for the return line, and one for the vent. The kit has two available Walbro fuel pump options. The standard 255 LPH pump or the 400 LPH pump for supercharged or 550+hp applications.
