I have a sets of new ductile iron main caps available for 360 main blocks. These are Mopar Performance R Block caps. . The sets include all 5 main caps. The center 3 caps are 4 bolt main. I have installed these caps on a stock block before by milling off the ends of the center caps to leave them 2 bolt. See pictures for the 3 modified center caps installed on a small block stroker engine. These caps are more stout than the stock caps and are an excellent upgrade for any high performance build. A line bore will be needed when installing new caps as well as some machining for the thrust bearing on the #3 cap and #5 cap for the oil seal.

Price is $320 shipped in the lower 48 states.
