Which one was quickest in 1972

i remember in 1968 the 340 barracuda was faster than a "B" body 440. i think the 440 3-2 bbl was not out yet. my friend had a new 68 340 barracuda. 4 speed. it was FAST. in that year the 4 speed 340 had ever so much bigger cam than the auto. it all so was the first year for the AVS carb. that had a flat spot off idle. easy to fix. but over all the rear gear is a lot of who is the fastest.
