2.66 low gear vs close ratio

AJ, I really do appreciate your knowledge on this subject. You brought up a ton of points I would have never thought of and explained the math in a way I can follow it. Thanks! Plenty of torque over a broad range shouldn't be a problem since I plan to stroke the 400. That .309 1st gear regular 833 and a GV looks like the way to go! Now I have another thing to start saving my money for. Going with an automatic in this truck is not an option since the dart is an auto. I wanted a 4 speed with this build.
