1968-1972 A-Body LS Conversion
This LS swap kit is made specifically for 1968-1972 Chevelle, Le Mans, GTO, Tempest, Cutlass, Skylark, and GS. 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 pan, 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. El Caminos use the Convertible part numbers since they use the same boxed frame.

Oil Pan kit
We 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.

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.
Oil pan kits come with our exclusive pickup tube girdle.
All of our stainless headers feature a collector merge-spike that creates a smooth transition from the primary tube into the collector. It reduces low pressure turbulence increasing the scavenging effect of the cylinders thus increasing flow and power output.
Mild steel ceramic coated headers coming soon.
MuscleRods Stainless Steel Headers
We have found that 1 7/8" is the best size header for most LS swaps. So, we now offer a 1 7/8" long-tube header in stainless steel specifically for this LS swap. These headers feature 3/8" flanges and very smooths bends that create a great raw stainless look. The 304 Stainless steel ensures maintenance-free longevity. The long-tubes feature a slip-fit collector that when used with stainless steel band clamps offer the best ground clearance in the industry. The collector merge-spike increases power in both the mid-length and long-tube. They include gaskets, bolts, and O2 sensor bungs.

EFI In-Tank Pump Fuel Tanks kits
There are two main fuel supply issues that arise when converting an early vehicle to late-model fuel injection: One is getting the fuel pump to live during long runs in high temperatures and the other is keeping the fuel pickup covered with fuel at low fuel levels. Our EFI conversion tanks solve both problems the same way the OEM manufacturers do by installing the fuel pump in the tank, and baffling the tank to minimize fuel slosh. Having the fuel pump in the tank keeps it cool, and a baffling system inside controls fuel movement and keeps the pump fed even at low fuel levels and extreme driving conditions. Another great benefit is that once installed, these tanks look like the originals. Click for more info.
Fuel Line and Regulator Kit
Our quick and easy complete fuel line systems includes everything needed to go from the fuel tank to the LS fuel rail. Includes P.T.F.E. braided and covered fuel line, an OE style fuel filter/regulator combo, line clamps, and all fittings and connectors needed. Standard kit is for 255 LPH pumps with a 400 LPH version also available. Click for more info

The all important steam port bung is welded into the upper part of the tank which lets your new LS engine vent properly. They also include a sensor port that can be used for a coolant temp fan switch. Excellent restoration type quality made in the USA. Available in bare aluminum or black.
