My '54 GMC 2 ton is without title right now so I'm not driving it,but as it's currently set up,my number cruncher indicates it'll cruise at about 80,with a full out redlined top end of 102,if the 302 can work up enough power. (It's a little ways from stock though.302 six,5 speed OD,3 speed OD,2 speed axle w/6.40 high)
