Well have you ever heard of the silver state classic Chris Kauffman preped a stock 5.0 with a belt driven super charger and it AVERAGED 173 MPH thats get to speed and slow down . Also Montana didnt have a day time speed limit for a while.

Where do you get 700 Hp from and a six wont do to much good as the final drive is just about the same as a t5 in fith the extra gear is between 4 and 5 which helps keep the speed up .
at bonnivile the gearing is key as 100 hp flatheads have hit 175+
ps you dont need top speed just keep it to the track .
Also that run was before i had kids and now i avoid street racing and other activities that would put others at risk.(except at the track)
