1970-72 Monte Carlo LS Conversion
This LS swap kit is made specifically for 1970-72 Monte Carlo. 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. 66 and 67 El Caminos use the Convertible part numbers since they use the same boxed frame.
