I would say maybe a little less than that due to the taller tires...

Gearing, and better aerodynamics. Lower coefficient of drag and less frontal area...less lift too, don't scare the **** out of you over 150 by feeling all floaty.

I've got an old Motor Trend with a Lingenfelter 383 LT1 Formula and it topped out at like 194 or so. I'll see if I can find it and scan it when I get a chance.

for one at that speed a cop will never catch you. and its awsome to know your car will do 150. just dont recommend it with the t-tops down.

i thought the stock limiter cut ya off at like 165. o well. any way i'm with grubby, no 150 with no t-tops. i've only gotten to bout 125, course our roads suck here. congrats man, it didn't scare u at all to be going bout 170 past a car? if not u got bigger cajones than i do.

At 155 that cop "way off in the distance" would be almost immediately on top of you if he was ahead of you. If he was behind, he'd be out of your vision just as quickly.
