So this car has a 400 ci motor putting out a whoppin 200 hp and 325 tq!!!!! Wow!!! My 3.0L BMW is rated at 300 HP and 300 Tq. 3.0L is 182 ci which is less than half the size of a 400 ci. I know technology has come a long way but that is ridiculous!!!!
It depends on the years you are talking about. In the early 70s, the Trans Am could be had with a 455ci/425hp motor and the 400ci had over 300hp. 1972 brought the first emissions which made drastic changes and by 1974 (with the "gas" crisis) American muscle had been completely emasculated.

As an example, I bought a new 1971 Corvette with the 350ci/330hp motor. In 1972, with smog pumps, etc. that same motor was 350ci/255hp. Another example was the Corvette 454ci motor. In 1970, the 454ci had 460hp, but by 1974 that same motor had 270hp. So things changed drastically.

By comparison though, your 3.0L motor in 1972 had about 176hp. That was the technology then. Comparing your BMW to cars of the 70s is very much apples to oranges.
