World Products 081100-4250 - World Products BB-Chevy Merlin III Cast Iron Blocks

Ideal for street, ET bracket racing, and marine applications, World Products applied almost 15 years of Merlin knowledge to develop these blocks, offered bare or race-prepped. The race version features a thoroughly-washed block, plate-honed cylinders to the bore size, and installed cam bearings and freeze plugs. Merlin III blocks have reinforced bulkheads and main webs, thicker decks, 100% compatibility with Mark IV components, and indexed lifter bores for optimum reliabilty. Their quality is superior to OE parts, especially because each block is CNC-machined to
QS-9000 specs using only two fixturing operations (thus avoiding tolerance stacking common to factory blocks from assembly lines).
