So this is a great Monday! Tore down a 2013 Grand Sport corvette in preparation for a SMP cam kit with a ProCharger and all the works, and discovered the carnage on the 5th Gen Camaro from the track day Saturday! We are slowly but surely bringing a few of our own builds to the table to compete with the locals and building a few really nice customers jobs at the same time! We got a few surprises in the works as well that just might become some National traveling competitors!

Well we had another good time last night at Swamp Bottom Dragway! We might not have been the fastest street car/truck there but we stayed with it and got a little luck on the tree but we put Ol Blue in the winner’s circle and she earned herself a little payday last night! She is finally starting to come around but still a long way to go!
