That old 440 in my Gtx, was a one in unlike any I had seen before or since in stock condition, super fast and very quick , my buddy was doing new car make ready at the dealership and said of all the other hp cars he had driven it far exceeded them all , so I took it for a blast and came back to work and bought it! Of course, to be fair about this, the older you get , the bigger the fish and faster the car , I guess! Oh ,but what fun it was to be Mopar Guys in the late 60’s and Chrysler was all in with it ! There were six Mopar guys in Conroe and everyone else were the other guys ! Our secret weapon, was an older guy , who was a Howard Hughes ,Master Machinist and good equipment! His son was one of us and he read about the tricks and we made them happen ! Oh btw , after a four day Super Stock Eliminator meet at Dickinson Drag raceway , she ,Shirley Shanahan beat me by a headlight and I was poorboying it and she had sponsers! Wish you young guys could have been there with us !
