Like yeah sure it’s impressive that the C8 Z06 makes 670 horsepower from a 5.5L V8, but how about the 1974-1976 Cadillac DeVille making 190 horsepower from an 8.2L V8?

For comparison, in 1934 Chevy offered a 3.4L I6 with 80 horsepower, the same efficiency as that massive big block from 40 years later.

I daily drove a shitbox 1975 Eldorado with the 8.2L while in college (2014 ish).
It actually was a fantastic car to drive. It has torsion bars in the front and air ride in the back and it sailed down the interstate like it was on a cloud at 80mph. The 190hp 8.2L was slow, but not so slow that it was annoying. It made enough torque to move a nearly 3-ton barge without much fuss. It was bomb proof reliable and did extremely well in the snow (3 tons and FWD helped).
They were great at what they were designed for - a surge of torque at part throttle/low RPM.
