With its Hemi-Crossram, Check Out the Rarest 1969 Camaro Ever

Wallpaper Description:

Sitting proudly in the super-clean engine bay is the only known surviving all-aluminum, Hemi 302 crossram in existence. It appears that some of the folks at Chevrolet’s engineering department were thinking to the future by using existing technology available at the time. The O- prototype, 327 block is straight from Zora Arkus-Duntov’s Grand Sport Corvette closet. Screw-in freeze plugs have been welded into the block to guard against possible failure caused by the high temperatures encountered during racing. The crankshaft and connecting rods are stock (but heavily massaged) 302 items held in by four-bolt main caps. Cooling is provided through a GM prototype aluminum water pump. The head package has its own unique story, which is steeped in Chevy engineering history with a twist of Daytona Beach
