I run a STR-14-6 with mechanical carbs. The motor is a .060 over 440 w/ Eddy heads, 10.7 cr, and a Comp hydraulic in a 66 Coronet. I bought the STR partly because I was told "It will never work". I didn't believe that. I'm knocking on the 10 second door w/ a best of 11.03 @ 119. I'm working on a weight loss program......
