'A-Body Showdown' ~ 1967 Dart GT 273/235 HP vs. 1968 Dart GT 318/230 HP
Race
Coming off the line and 'Out-of-the-Hole', the 273 with it's higher RPM's would gain an edge,
as the 318 would be forced to shift into 2nd-gear earlier.
This would allow the 273 to pull to a 'full' car length lead.
The 273/235 HP was strong at 'Early Mid-Range', and thru 2nd-Gear it would be able to pull
almost another 'Car-Length'.
The 318, peaking at 4500 RPM's would be forced to shift into 3rd-Gear earlier, as the 273 could
crank at 5500 RPM's.
The 318 was a strong 'Torque-Monster' at the 50 to 70 MPH Range, and would be able to hold
it's own with the 273 at 'Late Mid-Range'.
The 273, once hit 3rd-Gear, would have to stay in this Gear longer to pull into the RPM Power Band.
At the end of 3rd-Gear, the 273 would tend to 'flatten-out'.
This would allow the 318 'bigger cubes' to make up some minor ground at the Top End, but it would
run out of Carburetor.
Both Dart GT's running a 4-Speed, w/3.91 Gears 'Sure-Grip'
