Today, dollar for dollar, is the 318 faster than the 340 ???

Most of my cars came with 2.76 open gears. I replaced a lot with 3,23's and 3.54's.

I had a 1965 Dart GT that had the tow pack. It came with A 904 and 3.23 SG 8 3/4, heaver springs, 10 inch drums and a 20 gallon second fuel tank in the spare tire well. I stripped most of the tow package and put 4.10's in it. Drove it off and on when I was home from Germany on leave.
Then in 1984 I got stationed at Ft Gordon GA and drove, due to snow, the southern route 3500 miles from Seattle WA. SUCKED! But it was the only car I had.
