1968 Chevrolet Camaro SS 396 375hp L89 vs 1970 Buick GS 455 (Pure Stock Muscle Car Drag Race)
The first car is none other than a 1967 Chevrolet Camaro SS396 L89. The L89 took the high performance 396 engine, the L78, even one step further when Chevrolet put a set of aluminum heads on it. Sure, it didn’t really add any horsepower, and it was a VERY expensive option, but it did remove a decent amount of weight from the front of the vehicle. And Camaros can definitely use that! It’s a quick car, and it looks great! I’ll think I’ll add this one to my wish list… just like every other car we’ve featured.
The Camaro’s opponent is one that gets somewhat overlooked, yet, it definitely shouldn’t. It’s a 1970 Buick GS455. AN ABSOLUTE TORQUE MONSTER. The Buick also brings something that a lot of other GMs couldn’t; FAST WITH CLASS. I like it. I want it too.
