ENGINE BLOCKS AND COMPONENTS A. Cast Iron “R3” Race Engine Blocks Building on our heritage, the R3 race block family offers the latest in design technology along with the options to meet your speciﬁc needs. All of these blocks feature: • Process-controlled castings utilizing high-strength cast iron and a computer-controlled stress relieving process • 100% CNC machining with full statistical process control • Thick deck surface and 6-bolt cylinder head attachment (48° blocks) for improved sealing and reliability • Rough bore at 3.900” with various options that provide over-bore capacities up to 4.220” (in siamesed-bore versions) • Various options that provide deck height potentials of 8.900” to 9.560” • Tappet angles in both 59° (stock) and 48° (improved valve train geometry) are available (59° blocks are not recommended for use with roller tappets) • Thicker main webbing and pan rail for improved rigidity • 4-bolt mains in ductile iron, billet • 318/340 main journal size • Machined for pre-Magnum head oiling, as well as engine mounts P4876381AB Cast Iron “R3" Race Engine Block-Siamese P5007360AB Cast Iron “R3" Race Engine Block-Siamese P4876671AC Cast Iron “R3" Race Engine Block-Siamese P4876791AC Cast Iron “R3" Race Engine Block-Siamese P4876672AC Cast Iron “R3" Race Engine Block- Non-Siamese P4876792AC Cast Iron “R3" Race Engine Block- Non-Siamese P4876673AC Cast Iron “R3" Race Engine Block-Siamese P4876793AC Cast Iron “R3" Race Engine Block- Siamese P4876674AC Cast Iron “R3" Race Engine Block- Non-Siamese P4876795AB Cast Iron “R3" Race Engine Block- Non-Saimese
340 Replacement Engine Block (Not Pictured) Limited production of the original 340 block has made it very difﬁcult to ﬁnd in good condition. Why take a chance with a 30-plusyear- old block when you can buy a new one? This new casting includes the original 340 production casting part number with an “M” added at the end to identify the Mopar Performance 340 block. The block has a few cosmetic differences from the original 340 block, but it is machined to work with all 340 production components. Special features include brand-new castings made from high nickel cast iron for added strength (not a thin wall casting), 4-bolt main bearing caps and 340 journal size. It has thicker webbing and pan rail (like the 340 T/A), a thicker deck surface and thicker bore walls in major/minor thrust directions. Block is rough bored at 3.900" to allow various bore sizes from 3.910" to 4.080" size (ﬁnish bore and honing required). Deck height is approximately 9.600". Requires the use of oil ﬁ lter (PN 05281090BA). The 340 Replacement Block is ideal for restoration or where racing rules require a 340 block. It is not recommended for use with roller tappets, and may require use of late 1970s 318 motor mount (left side). *P5007552 340 Replacement Engine Block—Non-Siamese

340 Replacement Engine Block (Not Pictured) Limited production of the original 340 block has made it very difﬁcult to ﬁnd in good condition. Why take a chance with a 30-plusyear- old block when you can buy a new one? This new casting includes the original 340 production casting part number with an “M” added at the end to identify the Mopar Performance 340 block. The block has a few cosmetic differences from the original 340 block, but it is machined to work with all 340 production components. Special features include brand-new castings made from high nickel cast iron for added strength (not a thin wall casting), 4-bolt main bearing caps and 340 journal size. It has thicker webbing and pan rail (like the 340 T/A), a thicker deck surface and thicker bore walls in major/minor thrust directions. Block is rough bored at 3.900" to allow various bore sizes from 3.910" to 4.080" size (ﬁnish bore and honing required). Deck height is approximately 9.600". Requires the use of oil ﬁ lter (PN 05281090BA). The 340 Replacement Block is ideal for restoration or where racing rules require a 340 block. It is not recommended for use with roller tappets, and may require use of late 1970s 318 motor mount (left side). *P5007552 340 Replacement Engine Block—Non-Siamese
