The 350/265 Base is assembled with all-new, premium components, including a brand-new block with four-bolt main caps — a strength-enhancing feature most original and core 350 en¬gines don’t have. This all-new assembly is delivered with the oil pan and timing cover. It is also internally balanced and features the pre-1986-style two-piece rear main seal.
