what good is a transmisssion that cant be shifted over 6000rpm???

oh, its good for a show car. thats driven easily.

i want a muscle car that is driven hard. Cant run a 4 sp with steep gears on the street? Why is that?

I run 4.30's in my STREET DRIVEN cuda. 3000 rpm at 55 mph, or 3200 rpms at 60 mph is no big feet for me. thats right where my converter is solid.

if I calculate the cost saving from mileage going from 3200 rpm at 60 mph (9.5 mpg) to 2300 rpm at 70 mph (11.0 mpg if im lucky), I'd need to drive about 150,000 before I make up the cost of a $5000 overdrive system.
