    I have a few sets of new ductile iron main caps available. These are Mopar Performance caps. I have sets for both 360 main and 340 main blocks. The sets include all 5 main caps. The center 3 caps are 4 bolt main. These are the same caps that came standard on R3 4 bolt blocks. I have installed these caps on a 340 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 340 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 and #5 cap for the oil seal.

    Price is $220 shipped per set in the lower 48 states.

    PM me with any questions
