1968 '340' Barracuda vs 1968 '383' Road Runner

All contributors bring out proper arguments.

But I was trying to compare 1968 Mopars, that were classed in E/S or E/SA for
NHRA in 1968.

Weight-to-Horsepower range { 10.00 to 10.49 Wt/Hp }

The 68 Barracuda 340-S {Fastback}............ #3110 lbs ~ 310 HP = 10.03 Wt/HP
The 68 '383' Road Runner {Pillared Coupe}.... #3424 lbs. ~ 335 HP = 10.22Wt/Hp

This was after the NHRA re-factored the 340 from 275 HP to 310 HP in December 1967, before the 1968 Season.

These 'two' Mopars qualified for the same NHRA Class.
