A hair over 120mph when I tried to top it out on a long 5mi stretch of boon-dock road.
[edit] and that is after I drove it 600 miles of a 740 mile trip from OK to CO during 100+ degree heat (if it matters, I dunno)...

My 12a streetport turbo? Its 140mph+ forsure. I know it gets to 140mph with 7psi boost. I'll bump up the boost sometime.
But driving that fast is very unsafe with H-rated tires and the 1st gens are not that stable without more downforce from either wings or front air dams or both. I don't care about top speed when its easy to get past 130mph.

136 or 142 mph. Havent done the check of my 5th gear to know which is correct. Stock port 12A, MSD ign, stock carb, stock 79 manifold, carter fuel pump, holley FPR, low restriction air intake, 4:88 gears, long primary header exhaust, electric fan, underdrive pulleys.
