1970-1981 F-Body LS Conversion

This LS swap kit is made specifically for 1970-1981 Camaros and Firebirds. 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 subframe. It was designed around our 98-02 f-body GM oil pan. 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.

MuscleRods 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. 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.

Our stainless mid-length headers have 1 7/8” primaries with 3" 4-bolt collectors making great power for their compact size.

Smooth bends and transitions in 304 stainless steel.

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.

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 and mid-length 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.
