I'd like to do up an early A-body sedan with a modern 5.7 Hemi and 5 speed.

For now I'm happy with my '63 330 that's going together with very mild 440, 3.55's and sure-grip in the rear.

Last car I did like this got decent mileage (14-15mpg@70mph) on the highway and was very pleasant to drive around town.
