that will certainly help. My stock stroke 360 dipped into the 11.20’s that i took out of the car before last season started. Usually 11.40’s to 11.50. Weighs 3320 with me, all steel Dart and i am 320 myself. You wont have to short shift it. Should run 98% as good as its gonna run shifting it not much over 6k. There wont be 2 or 3 tenths upping the shift point a few hundred rpm. My cam was 260@50
