This LS has forged rotating assembly, Moroso oil pan, 11 degree LPC heads, and a Holley EFI fuel system. This 408 made 530 HP & 490 TQ at 6200 RPM on pump gas. The owner is installing a nice sized turbo which should increase the HP to 680. This LS will be installed into a Chevelle. After that we may see it on the Chassis Dyno in the near future.
