Replacement valley cover for customers removing DOD/AFM on LT1,L83/L86 engines. This item is extremely popular for anyone swapping camshafts in these Gen 5 engines. A perfect example of this would be race/retrofit customers who are switching to aftermarket camshaft & want to run traditional style hydraulic or solid roller lifters.
Note: Excludes LT4 and 19+ Truck Engines. (Basically not designed for the blower engines or the new 19+ engine that has DOD/AFM on all cylinders.)
