my 73 c-10 1/2 ton pickup will bury the new speedometer needle (120mph) with reletive ease, however you can feel the wind hit the truck in gusts, and it does have an effect.
My truck has a semi-built (heads,cam,exaust,intake) 350 v-8 with a TH-350 tranny 3.07 rear gears..
Soon to have a more extreme 350, Th-700r4 and 3.73s with an Eaton POSI
She's a brick off the line, but once she rev's a bit she's a screamer.
