I remember somebody constantly insulting me as an ignorant southamerican at dodge-charger.com ( the old board ) when I stated the standard engine on Rallyes was the 318. Still showing the dealers book and andvertisings brochures with the specs for the Rallye.

About the 340 engine on Rallyes. That was the only way to get 340s, buying a Rallye. So any 72/73 Charger with 340 is a Rallye by default. 360 on 74 since 340 was replaced for it.

On 71 the 340 was just available for the Superbee.

And Yes, a Rallye could be WL21 or WH23… even is true most were WH23 hardtops
