Ok, so I'm wondering the top speed on a 1979 Trans Am with the 301 Pontiac Engine. Has Anyone ever topped out theirs or read about it, I can't seem to find it anywhere.

Love these nearly impossible to answer questions.

Ok, weight, temp. humidity, wind speed and direction, elevation, gearing, tires, all kinds of factors weigh in on top speed.

But, for a best guess, I would say low 130's for a Trans am, on the salt flats on a decent day. Hows that?

I owned a 301 4bbl powered 4-speed 79 Formula with 2.42 rear gears, I never found a long and flat enough road to get it over 105, I think that was all it had in stock form, maybe with 2.92 or 3.08 axle it might have enough HP to go alittle higher.

I'd say you would be lucky to break 110 in stock form.
