What converter are you running ?? I use the MP .557 solid in the mild 906 headed 440 in my 63. I love it and I run 10.0 comp with quench as the pistons are the KB quench pad units. It has a Dynamic 9.5 street/strip converter that drives great and flashes about 4200 at the track. I drive it on the street and only adjust the valves once a year. Ron
