Spring Fever: C5R Racing Block

GM-Performance-C5R-LS-Engine-Block.jpg
The highest performance Corvettes built are used for the factory-backed race program, like the current C6R and previous generation C5R. 
And while the ZR1 packs huge power, the C5R and C6R are built to endure the rigors of endurance racing, and that begins with the engine block. This Gen III LS engine block is from the C5R Corvette racing program, and it’s the same type used to run the 24 Hours of LeMans. 
It’s a bare block, so there aren’t any performance specs, it’ll pack plenty of power once built. At $4,800, this block is a huge discount from the list price of $8,0000.
