Top Speed stock 5.7?

My tko600 equipped 73 Duster with a 400+hp 408 stroker and 3.73's hit 130 on the back striaght at Talladega in May, with the windows down and vents open. Still had plenty left, just ran out of straightaway. Took turn 3&4 at 109, smooth as silk. Oh, and my tank pickup was uncovering off of turn 2, I only had 1/4 tank of gas. Silly me, I should have filled up!

My 08 LS3 Vette, on the other hand, hit 163 and was still pulling! That was top in and windows up. Best I could get with the targa top off and the windows down was 145.

So with the windows up, I imagine it would have picked up 5 mph...
