Truck's Gotta Bite !

A couple of junk motors strapped down in the bed right over the axle will gain you some traction!

shortbeds hook up better than longbeds . my 92 406 gmc had 1.50 60fts , skimmed the front wheels w/ 410 gears and and 10'' hoosier slicks . wish I still had it , 16.1 mpg , and hi elevens , street driven.
