The Motown Iron Race Block is constructed using 4130 chrome molybdenum steel, which is known for its exceptional tensile strength and fatigue resistance.

Its construction from 4130 chrome molybdenum steel, raised deck design, and performance-enhancing features make it an ideal choice for serious racers and hot rod enthusiasts.
