392 hemi in a 64 dart?

Your plan could work with a rear axle move, stock motor location, and what ever light parts it takes to get the weight under 55 percent front if you are going to run 9.0 or quicker. At 8.80s I need a trans brake to hit the tires hard enough for a decent launch at 53 percent front. I had it at 50/50 , but it was too violent on launch, wild wheelstands. Wheelie bars 66 inch long worked but it would hit them so hard I could feel it lose traction.
The problem between street and strip is on the street the traction REALLY suffers as weight gets heavier on the front. At 50/50 you could feel my car pulling pretty hard; at 53/47 about half as hard, almost instant red line in high gear from a standing start. That is with a 15 x 33.6 slick.
If you are going to run mid 9s, 50/50 worked for me, but needed wheelie bars to limit wheelstands.
