1978-1988 G-Body LS ConversionThis LS swap kit is for (78-88) Monte Carlo, (78-83) Malibu, (78-87) El Camino, (81-87) Regal/Grand National, & (83-87) Cutlass. The center of this conversion is our engine mounts and crossmember kit. This mount kit includes new frame brackets that bolt into existing holes in the frame. Unlike most LS swap parts on the market everything here was made to work together, so you'll have clean mounting of your engine and not a mix of unrelated parts.
Our engine mounts position the engine so there is no steering interference, and our crossmember maintains the proper drive-line angle. There are many options to complete this conversion including, oil pans, headers, fuel system, cooling, front accessories, and wiring. Simply scroll down through the following part groups to see all that we offer for an easy, strong, and clean installation of your LS engine. See our installation guide for more info on this LS swap. Oil Pan kitsWe developed our MuscleRods high-clearance oil pan to offer the best combination of fit, clearance, oil control and ease of installation. Built to our specs by Moroso, the pan works with strokes up to 4.125' and retains the OEM oil filter location.
The high-clearance pan kit includes the pickup tube, gasket, hardware and our exclusive pickup-tube girdle. The GM LH8 Muscle Car pan can also be used with this conversion, but please be aware the sump will extend below the front crossmember. For this reason our high-clearance pan is a must for any vehicle that has been lowered.
MuscleRods Ceramic Coated HeadersOur ceramic-coated headers offer many features that are normally only found 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 great ground clearance.We offer several sizes so you can match them to your horsepower level. 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. Standard ceramic finish is polished silver, contact us for bare steel and black ceramic coated pricing. EFI In-Tank Pump Fuel Tanks kitsThese 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. The kit also includes tank straps, vent filter, gaskets, and hardware. They look like original equipment from under the car and are absolutely the best way to go when converting to EFI. 207-6680-04 78-88 Monte Carlo, 78-83 Malibu - 255 LPH pump $549.-06 78-88 Monte Carlo, 78-83 Malibu - 400 LPH pump $629.-04 78-87 Buick Regal EFI Tank kit - 255 LPH pump $549.-06 78-87 Buick Regal EFI Tank kit - 400 LPH pump $629.-04 78-87 Cutlass 4 door EFI Tank kit - 255 LPH pump $549.-06 78-87 Cutlass 4 door EFI Tank kit - 400 LPH pump $629.-04 81-88 Olds Cutlass EFI Tank kit - 255 LPH pump $549.-06 81-88 Olds Cutlass EFI Tank kit - 400 LPH pump $629.-04 78-81 Cutlass Notchback Tank kit - 255 LPH pump $549.-06 78-81 Cutlass Notchback Tank kit - 400 LPH pump $629.00.
