GM is putting back into limited production the legendary race-inspired ZL1 engine with only minor changes. Featuring an aluminum block and cylinder heads, the 427 / 7L was rated at a respectable 430 hp and 450 lb.-ft. of torque, but when Motor Trend dynoed it independently, they got 525 hp form it.
The 427 examples of this engine will be made with the same machinery (recently rediscovered) the originals were made of. They will surely go for a pretty penny, especially considering that a 1969 Corvette equipped with a ZL1 and slicks did the quarter mile in 10.89 seconds.
Of the original, there were only 2 Corvettes, and 69 COPO Camaros with the ZL1.

This is really sick. This engine is a ballin' engine and I would proudly put it in whatever the hell car I owned.
