The primary difference between a two-bolt and a four-bolt 350 refers to the engine block's design, specifically the number of main bearing bolts used to secure the crankshaft. A two-bolt 350 has two bolts per main bearing cap, while a four-bolt 350 has an additional set of bolts, providing greater strength and stability. This makes the four-bolt version more suitable for high-performance applications, as it can better withstand increased stress and power. Overall, the four-bolt design enhances durability and performance potential in demanding conditions.
