I've got a 3.73/700R4 combo in my '68, and first gear is way lower than I need it to be. The 3.42/700R4 combo in my '89 makes first gear more reasonable, but then the jump to second gear is big for that mild TBI 350. The 3.73 is a little more fun to drive, but the 3..42 seems better for gas mileage.
