I pulled a 351W from a truck and will plan to build it for a kit car project.
I briefly spoke with a machine shop, about boring it out to 4.125, so I can build a 427. They told me no way would I be able to bore a standard block that much, they said the most I can go will be .060 over. That will leave me with a 418ci.
I told him everyone is doing it, they even sell crate engines. He said they are using aftermarket blocks, from Dart.
Has anyone else been through this? Can you verify?I'm planning on calling a couple of other shops, just to be sure.
