3.23 or 3.55 Behind a 318

Anybody remember a 65 Pontiac Parisienne 2+2, with a two speed slushbox that would hit 60 in first gear, or 70, or maybe 80? But he it didn't lose any time to shifting in the zero to sixty, and it had no traction issues either. I think those PGs had a 1.76 low gear. That's like a third gear in a TA trans
But shoot, just about any 13 year old kid on a bicycle could blow it away off the line.......
I shift out of first gear at 60 mph with 2.45 gears, and that is not revving the stock 360 high, maybe 4900 rpms??? Still cuts 1.9's 60 ft.
