The car is a PHS documented RA IV Judge. The block is a 400 block. I do not know whether or not it has 4-bolt main caps, as I've never had it apart. The engine and drive train had been recently rebuilt before I bought it. It is not difficult to convert a 2-bolt block to a 4-bolt, so even if it has 4-bolt main caps, it may still not be an original RA IV block.
