|Note: Starting in 1972, the "net" horsepower
rating system went into effect and meant that the motors were tested
with all their equipment attached, which resulted in lower horsepower
numbers, making them appear to have less power than they actually
had. The auto makers had to start lowering compression ratios in
1971 and this resulted in some horsepower loss, but it wasn't
until 1975 that muscle cars were dealt their final blow.
Compression was lowered even more to allow cars to run on unleaded
fuel. Big block engines became extinct, and the smaller engines were so
underpowered it was pathetic.
