2.73 ratio is likely from a car with an automatic trans. Thats pretty high ratio for a stick. Still, I'd rather be to high behind a T5 stick than to low because the 1st gear trans ratio is all ready super low.

With a .6 over drive and a 2.73 you could shoot for a 200 mph top speed with a "little work" to the engine...

Yea, a little work... Like maybe around 800 HP to hit 200 mph with our flying bricks. That's assuming you'd find a way to keep it from going air borne.

SPF with a stock Roush 427R (except for very tweaked AD 750cfm Holley based carb), 3.27 Torsen rear gears, 295/15 Avon rear tires. Best 1/4 mile time: 11:37 / 124.9 mph. No idea what 60mph times are, but not that great I would expect. 60 ft times are nothing to write home about. No action without traction.

Probably everyone on this forum realizes that a 2.73 rear axle is good for top speed, and bad for acceleration. The title of the thread is "0 to 60 time." The point I was making is that with a stock 302, and an axle ratio that hinders acceleration, 0-60 times still in the high 4 second range are fairly respectable, and that drivetrain leaves tons of room for improvements/modifications.
