A new vehicle has broken the highest horsepower record for naturally aspirated engines.  The V8 in this truck puts out over 700whp. 

The truck is a Pro Stock 1956 Chevy Truck. 

With a parachute and wheelie bars, this is a very fast ’56 Chevy.  The owner/driver hopes to break into the 8s with this setup. 

Under the hood is a fully built 565 cid Chevy V8. 

This engine is running at 14.7 to 1 compression.  The list of parts is extensive and from the best component manufacturers.  Power is transferred to the ground through a Turbo 400 with 4:10 gears.
