Not Ranked
I've done the .040 over deal before - I mean hey - are you gonna scrap a 427? I don't think so. The last couple were sonic checked and both got a short fill of hard block to stabilize the cylinders. Just enough to go to below the core plugs.
Both sonic'd around +/- .080 right where the floor of the water jackets joined the cylinder jackets, so the short fill gave some support. They both seem to cool OK on the street, and one of them made 613HP and ran into the 10s in a '65 Mustang. The other is in a Cobra and just cruises around Toledo....
