For any real Z24 enthusiasts, this article is a little misleading (and offensive!!!).

The Cavalier Z24 didn't get one of these until 1995 - 99. And these were rated at 150 hp / 155 lb·ft pretty far from the 190 hp max.
Previous to this, Z-24s had either the 2.8 or 3.1 6 cylinders.
If you say Z-24 to anybody that knows the Z-24 from the cult following days, they are going to think 2.8 or 3.1.
Now these sound pretty bad:
1985–1989 — 2.8 L OHV MPFI V6, 120-130 horsepower (125 in 1985, 120 in 1986, 130 in 1987, 125 in 1988, and 130 in 1989) (I had an 89, 2.8)
1990–1994 — 2.8 L OHV MPFI V6, 130 horsepower (Mexico and Venezuela only, *Colombia used a version of 116 hp.
1990–1994 — 3.1 L OHV MPFI V6, 140 horsepower (100 kW)
But the regular cavalier at these times only had:
1983–1989 — 2.0 L OHV TBI inline-4, 86 horsepower (1983–1984), 88 horsepower (1985–1986), 90 horsepower (1987–89)
1990–1991 — 2.2 L OHV TBI inline-4, 95 horsepower (71 kW)
So.... 86 hp to 140 is a big difference in such a small car, also at this time the Monte SS had 180 hp so the Z-24 isn't looking that bad...
Curb weight of Z-24 vs Monte:
2,558 lb (1,160 kg) (Z24 coupe) - 3,239 pounds (1,469 kg) (SS)
Monte Carlo SS weighed 700 lbs more and had 40 hp more.
I am sure that torque is a different story. (The Monte is a great car, not putting it down. Just saying for the Z-24 haters...)
Ok I kind of found the torque story:
it is approximately 170 in the Z-24 to 240 lb·ft in the Monte.
The Camaro and Firebird had basically this same engine but in longitudinal form, without the Z-24 aluminum heads.
Curb Weight: 3100-3500 lbs
This is why a Camaro with a six cylinder isn't taken seriously. The cavalier was probably faster with the same engine. Not the case against today's six cylinder Camaro.
