I'm in 18th spot and am still patiently waiting for this jewel. Not in a rush, as I know Jamie is doing it right. I also run 3.54's and a 29 inch tall tires, but still, dropping almost 800rpm in 4th at 70 mph would bump my mileage significantly...not to mention calming the entire driveline down. I'm currently spinning 3000 rpm at 70 mph.

I don't get how you guys run 4.10's or lower on the street with massive torque and the inherent traction issues. Even with gooey drag radials I always spin 1st & almost always halfway through second, and I'm hitting 70+mph at the end of second.

Squatting in 3rd after a downshift from 4th at 70 mph with a bit of tire smoke......3rd lasts about 2.5 seconds or less up to 105 mph from this speed. Gotta love stroked big blocks and twin disc McLeod's.

I'm worried the car would fly with a 5th gear though.
