I have 3 sets of Mopar Performance 360 main cap sets for sale. These are nodular iron MP parts and are sometimes machined and used in 2 bolt 360 blocks to beef up the bottom end a bit. The first 2 sets have 2,3,4 and 5 caps. The third set has a heavy 4 bolt for the 3 thrust bearing but the 2,4 and 5 are already 2 bolt caps. Someone bought several sets and used a couple of the heavy caps for their front cap I assume. They are in their original boxes. 125 each obo for the 2 full sets and 75 for the mixed set of MP 360 caps. plus shipping. These are stronger than factory caps. Shipping from 50316 Des Moines, Iowa.
