Mast Motorsports Ls7 Crate Motor Cylinder Heads
|
Like the cylinder heads, the LS7 block is based upon the C5-R engine design that powered the factory Corvette race team to multiple American Le Mans Series championships. It's cast from rugged 319-T5 aluminum, and features doweled billet steel main caps. In conjunction with ARP studs, the caps firmly hold the Callies/Compstar 4340 forged crank in position.
