Inquiring Mind?
Being a fairly new C4 owner (June of 05, bought a low mileage 1989 - 32,500 miles) and it was affordable, anyway it appears as if through the 80's the Corvette was downgraded (horsepower), not knowing a better term. The horsepower was greater prior to the 80's and greater after the 80's - what took place??
I know as each year goes by - the technology becomes greater.
I have no complaint with the 1989 nor the L98 - it is still a workhorse and with a few extra buck, it will a run a little quicker.
But what's with the 80's?

In the eighties the Corvette was still recovering from the smog era of the mid to late seventies. The 1975 Corvette had an engine making only 165 horsepower, but as the years went on and technology increased (especially with the introduction of the TPI in '85) horsepower increased also. The mid to late '80 vettes may not have incredibly high horsepower number but the torque numbers were very impressive.

During the seventies, the automakers had to deal with the new emissions requirements and, as a consequence, the power output took a dip.
The biggest cause of the smaller numbers, however, was the way they determined those hp numbers. During that same time, the SAE standards changed and even though a particular engine did not change, the way the power was measured did... and it resulted in lower numbers for the exact same engine.

And from that point forward, HP numbers were on a steady increase until they reach where they are today.

With the above. Remember that in the '70s they were trying to pass emissions with carburators and in the early 80's electronic fuel injection was still a new thing. Just like tires, brakes, and electronics in general are so much better now than in that era.
