1996 LT4 Small-Block Chevy – The Finished Classic SBC?

When the Cadillac-derived Small-block Chevy engine first arrived in 1955, I’m certain that Ed Cole and his team of Chevrolet engineers never imagined that their efforts would have such a profound and long lasting impact on the automobile industry. The little 265-cubic-inch engine had just 162-horsepower. By 1970 the 350-cubic-inch LT-1 engine was packing 370 gross horsepower. Beginning in 1973 Gm started rating their engines in “net” figures making it look as if the legs had been cut out from under all of their motors. While it’s true that there were emissions restrictions and reduced compression, the “net” power ratings were in real-world terms, closer to reality.

From ‘73 to ‘96 it was a long slow slog, but the last SBC to use the basic original design was the 330-horsepower LT4. So, what would be the ”gross” horsepower rating of a ‘96 LT4? That would be anyone’s guess, but somewhere close to or over 400-horsepower would be a good guess. Read More

The introduction of the C4 Corvette in the Fall of ‘83 was a much anticipated automotive event. Times were tough through the ‘70s and no one anticipated in ‘68 that the new Mako Shark-inspired car would have a 15-model-year production run. And when you consider that the car was riding on a chassis designed in ‘60-’61 for the C2 Sting Ray, it’s all the more amazing that the late C3 cars set all-time sales records.

Just like all Corvettes from the beginning, the C4 was a car that was in constant evolution. Every year, Corvette Chief Engineer, Dave McLellan and his devoted crew of engineers and stylists made small improvements, with an occasional big leap forward. Little did we know when the C4 was first shown at the end of ‘83 that this Corvette generation would last almost as long as the C3 generation – 13 model years. Read More
