BRP Hot Rods makes Muscle Rods LS swap kits and LT swap kits for GM cars and trucks from 1955 to 2005. We are based in Cumming, Georgia, and started out as Brewer's Restoration and Performance. Every Muscle Rods conversion kit was developed on real project cars, and we sell the swap parts to finish the job.
