400 engine, weird pistons, strange object attached to cam!
Recently bought a 1970 lemans completely disassembled. Car was in very rough shape but came with a 400 and a turbo 400. Apparently I was at least the 4th owner of this forgotten project. Clearly hadn't been on the road in at least 25 years. The body ended up being scrapped but yielded up some parts. The 400 was dressed with an hei distributor, headers, Mickey Thompson valve covers, edelbrock p4b. Ripped it apart today and found the inside of the engine spotless. My only questions was about this weird thing on the front of the cam, timing oiler maybe? It's very off centerAnd also the pistons have I machined divet in the center of the valve reliefs. Never seen this before. Pistons are machined aluminum. The block is a 69' 9790071, letters XH on front of block. Heads are 62's December of 68. Seems to measure stock 4.12 bore, stock 3.75 stroke. Anyway information about the pistons or cup shaped object on the front on the cam would be greatly appreciated.
