1963-1972 GM Trucks LS Conversion
This LS swap kit was specifically designed for 1963-1972 GM ½ ton and 3/4 ton 2wd and 4wd trucks and SUVs. 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.

BRP Oil Pump Pickup Tube Girdle

Use with a little Locktight and it’s cheap insurance against an engine meltdown. It comes with two longer bolts for install.
Muscle Rods Ceramic Coated Headers
Our 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. Our long tube headers do not work with 4wd. Includes gaskets, bolts, reducers, and O2 sensor bungs. Standard ceramic finish is polished silver, contact us for bare steel and black ceramic coated pricing.

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 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. They 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 and they include gaskets, bolts, and O2 sensor bungs.
120-6795 1 7/8” Stainless Steel long-tube headers (2wd only) $1049.00
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.
