273ci thoughts?

Graphs and data from 1967 Dodge (USA) Dart 270-Custom Hardtop full range specs
Lots of comparisons and metric heavy graphs.

318-2 edges out 273-4 from raw data. 273-4 pulls ahead after 100MPH due to higher revving potential of 273-4 cam profile and solid lifters.

(SORRY, DATA DID NOT SHOW UP IN GRAPHS)

Fun fact, 273-4 had a higher top speed due to camshaft profile and higher solid lifter RPM potential. Simulation says 68 318-2 would beat 67 273-4 by 21 feet at 1/4 mile with a slower MPH but faster ET.
Looks like both 2bbls run out of cam at 4200
