CHEVROLET PERFORMANCE 6.6L L8T GEN V LT CAST-IRON BLOCK

Chevrolet Performance has introduced a L8T cast-iron GEN V engine block that is very likely completely new to even the most knowledgeable enthusiast. This 6.6L production block is the foundation for your direct-injected performance engine that may see more horsepower than a lightweight aluminum block was designed for.

Additional features:

• Direct replacement for 2020 and later L8T 6.6L gas engines used in Silverado HD trucks.
• Production cast-iron casting finished with 4.065’’ (103.25 mm) cylinder bores.
• Used with a 3.86’’ stroke crankshaft in production engines to produce 400 cu in. (6.6L) displacement — the largest displacement in the LT engine family.
• 9.240’’ deck height.
• Delivered bare with regular-production six-bolt main caps.
• Regular-production oiling circuit.
• Includes provisions for direct fuel injection.
