You got to put in 91 or better octane in newer cars to see a difference. All new cars have a minimum of 10.1 compression some are even higher. Your old carbureted engines with vacuum advanced timing were 8.1 compression
Example
Corvette museum
The new LS2 was the most powerful standard small-block engine ever offered in Corvette. Its features include: all new 319-T5 aluminum deep-skirt block casting with cast-in-place iron cylinder bore liners and cross-bolted main caps, cylinder head design derived from the C5 Z06, Camshaft lift increased to take advantage of increased head flow, revised exhaust manifolds that are 34% lighter, compression raised to 10.9:1, and more powerful engine controller that incorporates all electronic throttle control functions. The 2005 Corvette can go up to 186 mph, which was faster than any production Corvette in history. It reaches zero to 100 km/h (62 mph) in 4.2 seconds, 4.1 with the optional Z51 Performance Package.
