Legendary Big Block Chevy engines, particularly the aforementioned, expanded more in 1970 to reach a massive displacement of 7.4-liter or 454 cubic inches! Can you just imagine how huge are the cylinders inside and how the move up and down in the household? That’s amazing!

But what is even more amazing is to see a 454 Chevy engine first start after 30 years! To hear the breath of 450 horses and feel the massive torque of 500lb-ft shaking the ground! There were rumors back in those days that the engine was underrated and was actually delivering 500HP, but there are no evidence to support these rumors.

Actually this engine mounted on the 1970 Chevrolet Corvette was delivering 390HP but as we said it was underrated and directly from the factory was producing 450HP.

But that’s about the details, let’s see how many horses are alive on our engine in the video, just look at him how tortured he looks like, like he was mounted on tank in during some war! But the after once he was started the real big block V8 sound raised! Amazing after so many years he still sounds badly!

Listen to the owner on the video what he has to say about it!
