The truth is this. The '71 engines were actually the beginning of the low performance engines. Most were taken down a bit in compression from the '70 models and therefore lost a bit of horsepower. The '71 and '72 models were actually quite similar to each other with the exception of a few models. The real reason for the large discrepancy between horsepower for the two years is that starting in the '72 model year, manufacturers were required to rate engines in SAE net horsepower. Before this, they used gross horsepower ratings (at the flywheel with no accessories, etc.)

The death of the muscle car was brought on by a few things. # 1 was emissions laws. You also had the rising costs of fuel and insurance. there are more detailed reasons then this just type in yahoo search the history of the muscle cars. If you enjoy reading you can stay busy with this information all day.
the question you have on the 1972 dodge charger engines power loss, is do to the compression racial change in order to meet emission standards the engine became more and more weak in 1971 the standards where not in forced yet.

The govt. came out with EPA regulations that seriously castrated the engines after 1971. Ford, Dodge and Chevy all got slammed with the new regulations. No more Hemi, 440 Mag, or the big horsepower Ford and Chevy engines. But they could be massaged to produce power. But I still say I will take a Hemi any day.

Fuel shortage and insurance companies---god, I hated waiting in those long lines. Most places you could only buy gas on odd or even days depending on your plate number. limited to 10 gals, and gas stations closed on Sundays. Also insurance companies started flexing their muscles---would not insure many engine combinations.
next major change was 1974/1975 with unleaded fuel, catalytic converters, and emission laws that went into effect

Because of the gas shortage of that time the car companies were trying to make more fuel efficent cars

the compression ratio is low
due to global oil shortage they made the engine run on lower octane petrol
previously 100 octane then down to 92 octane
