    Manufacturer's Part Number:

    These blocks are made from high strength cast iron and are heavy-duty pieces with extra stock for improved strength. All of the blocks include 4-bolt main caps on the center 3 caps (with ARP main cap bolts). Most of the blocks come with a Siamese bore water jacket and some have the full water jacket. The 48° tappet bore blocks come with a 6-bolt cylinder head bolt pattern. The 59° blocks have a 4-bolt pattern for the cylinder head. .

    This package includes the engine block assembly with main caps, main cap fasteners, and the block hardware kit. Some of the block hardware is installed in the block and some is included in a separate package with the block.

    The R3 and R4 blocks are designed for use in racing where the engine builder does most of the final machine work (i.e. boring, honing, and camshaft bearing installation).
