My Wifes Ramcharger with a stock 2bbl, single plane intake, and 70 truck manifolds will outrun your dart 0-60, with a crane 270 low lift 119$ cam and lifter set cam........ (3.55 gears may have some to do with that, but it is still a heavy brick)
The stock 318 cam is too small for gas mileage even. :icon_smi: No joke.
