You can see the crack in number 6 hole there, a crack here along the back of the wall. So that means this block needs to be pulled out of the car. If it was a replaceable block, we would throw the block out and build the engine around a new cylinder block. But this block is a real rare one and I don't--people say they make a different block that we could use. But would it be in a Ford, there's always going to be some little issue that's going to be slightly different from one to the other. There's going to be a bolt hole different. For the power-steering pump, there's going to be a different shaped port for the exhaust. There's going to be a different configuration for the distributor. Something is going to be different, and it will end up costing us more grief in the end. So we'll take this block out. We'll pull the motor out as it is, and take it to a machine shop and probably have the entire block sleeved. They'll punch out every single cylinder and put a sleeve in it. It's kind of a racing application but it's probably, financially, in the best interest of the customer here to sleeve this whole block and reuse it. That would be the strongest, most dependable, least variables. We know this block fits and we know this block works. We'll just go ahead and repair it.
