Hi, A friend of mine Dan Soliz @ Hill Country Performance has started a series of technical videos on building flatheads. So far he has covered block selection, magnafluxing and pressure testing. The block you see in the video is my 59L he is building for my roadster. (And when he mentions going through 10 blocks to find a good one, yes that was me.) Thought some of you would find it interesting. https://www.youtube.com/channel/UCVVLIJLIKzOJ5W-VCAGF9MQ Thanks, --louis
