I remember dyno day with my 340. Motor started after one crank. My numbers were less than yours but I was using stock 2.02 J heads and an 800cfm eddy performer. Still cranked out 390hp at 410lbs of tq. With an A904 transgo shift kit and Hughes 3200 stall converter it is down right fun in my 69 Dart. The 800cfm carb helps at the end of the 1/4 mile. I wonder if this would make it faster...
