Corvette Automotive History - Remember When

Thoughts From The Automotive Past: 1975-'81Most of us veterans remember 1975 vividly. Well, at least as Corvettes go! We all liked the new capacitive-discharge high energy ignition (HEI) because more spark to the cylinders meant more overall efficiency with a little extra power, too. We didn't like the new 2-1-2, catalytic converter exhaust system. Both head pipes merged into some sort of emissions-removal box, exited at the rear of same, and then split back into dual exhaust pipes. But when all was said and done, it was a great item and very good for Mother Earth. Tests also revealed that horsepower losses on the already low-output 350 engine were in the neighborhood of five percent.
