360-383 A-debate...max builds need not apply.

Did you mean 383 is standard engine in challenger r/t ?

I thought so, yes, but have since looked and was wrong.

It was the ‘71 and ‘72 Road Runner that I was thinking of, not the Challenger/Barracuda. 383 was the base motor and the 340 was an extra cost option.
