Do I need a new converter?

What does it weigh? Have you tried leaving at idle or 1500 or so? I think a good converter would be a good investment. I also think a good single plain intake would help.

Years ago I ran a 340 in my 69 Dart, it ran 7.24 @ 94 mph at 3240# on pump 93. It was .030" over, 11.4-1, Ross flat tops, Eagle SIR rods, ported edelbrocks, Hughes hydraulic, 237/242° at .050, .584/.592" lift with 1.6 rockers, Weiand X-Cellerator with a Quick Fuel Q-750, TTI 1 5/8- 1 3/4 headers, 727 with a CRT reverse manual valve body, a 9 1/2" Edge Racing converter that flashed 5000 using the method Dwayne mentioned above, 8 3/4 with 4.30 gears and 275 M/T radials.
