1968 Hurst Olds 455 vs 1969 Chevrolet Chevelle SS 396 375hp L78 (Pure Stock Muscle Car Drag Race)
The first car is a 1968 Hurst Olds. Oldsmobile knew the people wanted a big-cube engine in a midsize car, but GM made that impossible with the 400ci limit (later removed in 1970). However, when Oldsmobile joined-up with Hurst, they would ship the cars to Demmer Engineering in Lansing, Michigan where the old engine was removed and swapped with the breathtaking 455ci BEAST. Since it wasn't completed in a GM plant, GM looked the other way. You like torque? It's got just a little.... 500 lb-ft. Horsepower? 390. A surprisingly good handling car as well, and it even had front disc brakes. The opponent is no slouch. You're looking at a 1969 Chevrolet Chevelle SS396. However, this one is even more special, because it's a L78 car. Yes, a VERY underrated 375 horsepower. Those cars can take some abuse. Both great, I want 1 of each (or maybe 2 of each?) in my garage.
