Hi Guys,

A question for the experts out there. I disassembled a stock 460 that I pulled from my '93 F350. I'm the second owner of the truck, bought it with relatively low miles (~50k) back in '95. The engine hadn't been rebuilt before I bought it, at least to the best of my knowledge.

Looking in the lifter valley, I see the numbers 2, 3, or 4 written next to each cylinder, as seen in the picture below. I'm curious, can anyone tell me what these numbers might mean? Think they are from the factory, or do you think the engine was opened up by the previous owner? I checked and the cylinders are still stock diameter...not overbored. Would love to hear your thoughts!

Thanks for your thoughts and opinions Guys! Tootsie pop...I LOL!!

I wondered about the clearance cuts for the pushrods too?? Would one do that if the decks weren't 90* to each other? Their depth of cut gradually decreases going from cylinder 1 to 4.

I looked closely at the block and found several codes punched in:
2231H -- on the rear china wall, near oil pressure gauge
E1422 -- on the front china wall, near the distributor
2H19KB -- on the front face of block
Do these mean anything to you?

Starting to think my block got some attention before I bought the truck. :unsure:
