The pin came out of that single bolt solid roller Isky 505C cam 5 or 6 years after I put it together, I don't have a clue on how many miles or street races where on it I had another BB Mopar motor customer have the exact same thing happen on a Isky 1012B single bolt solid lifter(flat tappet)grind, both motors bent a bunch of valves I've sold and installed a bunch of single bolt cams from other cam companys and none of them ever had the pin come out OP, make sure and buy and use a cam washer big enough so it hangs out over the edge of the alignment pin hole to keep it in there
