Are you planning on installing an LS swap in your 1949-54 Chevy car? Here is what you need. This kit comes with our very popular engine bracket kit along with our LS adaptors. The LS adaptors will bolt to your engine and allow you to mount the standard GM rubber mounts to them. This will allow you to drop your engine right down on our frame brackets. Very easy install, no guess work. The adaptor brackets are adjustable as well.
