As stated, front end loose, rear set around a 50/50 setting, if leaf springs add pinion angle, put weight in the back, radial will be tough to hook, come out the hole soft and roll into the boost. A bias ply would be better but I see not in your cards right now.
I had a 1993 Dakota with a 408 and 275 shot of juice that I grudged race back in 2010. Made a good bit of money off it with 28x10.5 tire and stock suspension. Asphalt will want a lot of rear squat and power brought in easy, I doubt the trans brake will work very well on the asphalt, I always foot brake mine.
