It features siamese bores (4.000" or 4.125" unfinished) and extra-thick decks to ensure a reliable head gasket seal. Blind head bolt holes contribute to the block's structural integrity. This block offers clearance for a 3.75" stroke with steel rods and is designed to accept commonly available 350 main journals.
