The Ford Barn - View Single Post - Replace Flathead with Y-Block?

While the early 239's and 256's had some strange issues with oiling the top end, the later Y-blocks did not... provided the oil passages to the rockers were clean and the oil was changed regularly. At least none of mine ever did. See the Y-block Guy's videos on youtube and do some of your own research on the issue. There's lots of "haters" out there...

As far as Y-blocks "not breathing", do a search for what Karol Miller did with his '56 at Bonneville back in the day.
