Reply to 4.88 gear
The fuel shut-off is at 7000 rpm. The Cobra peak horsepower is at 5800, powerband extends to 6300-6400. Anything over 6400 is a waste of gas with stock cams.
The gear shifts at 6400 RPM are 1st at 30 mph, 2nd at 50 mph, 3rd at 75 mph, 4th at 100 mph, and 152 mph topend at 6400 rpm in 5th.
I don't plan to cruise in second gear at 55 mph, I'll use 4th and 5th.
This will be a strictly street use car with 4.88 gears. Cool, eh?!
I figure, why have an overdrive and use it for economy when it can be used for evil!!
The highest posted speed limit 70 mph on the interstate. I just plan to get to the speed limit (+/-) really quickly!
