World Products Merlin IV Engine Blocks
World Products has made improvements to virtually every area of the new Merlin IV engine blocks—with the goal of producing the most technologically advanced and best-performing iron BBC block available today! New features include thicker main webs for increased strength and thicker cylinder walls which are nominally .310 in. @ 4.600 in. bore. In addition to the standard BBC 9.800 in. and 10.200 in. deck heights, new heights measuring 9.500 in., 9.850 in. and 10.250 in. are now available. The World Products Merlin IV engine blocks are also available with a 2.120 in. BBC cam journal and standard .842 in. lifter bores, or with a 2.283 in. journal for a 55mm Babbitt cam and .904 in. lifter bores. World Products has added a front oil feed for dry sump systems, and relocated the lifter oil feeds and restrictor provisions to the front of the blocks.
