The cam and lifters were pretty worn so I tossed them. It appears to be a standard bore using my micrometer, 4.04, but a machine shop would have to make that call. No idea on the mileage being how it was transplanted into a 72 Roadrunner. Take a look at freightquotesonline. I had a 450# spot welder shipped from a residential address to my address by FedEx for $359 last October.
