I want to trade my used Mutha Thumpers with phasers which have 5k miles on it for Comp Cams NSR (127200). The reason is because I don't have the Mutha thumpers Stage 2's in yet cause I can't afford to have them installed and tuned. I wanted the Comps (127200) cause they don't need the tune and it would be more affordable for me to do. Please let me know if you are interested in the trade and also LMK how many miles are on your Comp Cams as well. Thanks!
