Introduced in 1967 with the same bore as the 327-CID and a stroke of 3.48-inch. In 1986 there was some changes to the crankshaft and rear main seal so crankshafts from pre 1986 blocks will not work in newer blocks without an adapter because of the new one piece rear main seal. The max Safe-bore for the 350-CID is 0.040-inch. All 4.001-inch bore blocks can be bored 0.060-inch with a 2% chance of being scraped due to thin or porous cylinder walls. The Second Generation small-block debated in the 1992 Corvette with reverse flow cooling.
