Pontiac BUILT a 640 HP Hemi in 1970 & BURIED It — Plus 9 More INSANE Engines!

Detroit engines that broke the rules: ranking 10 bizarre powerplants that manufacturers should have never built.
The automotive industry typically favors sensible designs that pass emissions and fit under the hood. However, during the golden age, engineers occasionally ignored the formula, creating mechanical oddities that defied conventional wisdom. This ranking explores why these projects were greenlit and the risks involved in pushing boundaries.
We analyze the design choices behind these classic powerplants, ranging from catastrophic failures to surprising successes. By examining this unique slice of engine history, you will gain a clearer perspective on the questionable decisions that shaped mid-century automotive engineering. Whether you are a fan of heavy-duty workhorses or high-performance builds, this breakdown provides context for the strange machines that left a mark on classic car engineering.
