For an engine rebuild, I highly recommend Mancini Machine in Westminster, MD. He rebuilt my '66 440, and it is wonderful. See my thread "The Saga Begins.". Lots of info there about the shop and build. Let me know if you are interested; and I'll provide contact info.
I don't think so. Years ago Mancini had a big shop near Baltimore. That shop is closed. Mancini built a new small shop next door to his house in Westminster. That is where my engine was done.
