“How much horsepower did the 1970 Pontiac GTO have?”
The 1970 Pontiac GTO came with a standard 400ci V8 engine rated at 350 horsepower. There was also an optional Ram Air IV version rated at 370 horsepower. The specific car you’re looking at has a non-original 400ci V8, so it could be either specification depending on what engine was swapped in. Would you like me to help you find more details about this particular GTO or look for similar vehicles?
