I'm now making some progress on getting my '62 261 ready for installation into my '40 sedan. I have the block ready and will put the crankshaft in this week. The bore and the crank journals are all standard size. I'm using the 261 head for now, but might switch to a 235 head later. The rings that I'm using are chrome.I have never used chrome rings before. I hope I can get them to "seat". The car has been in the Garage since April and I miss driving it. My goal is to drive it again by Thanksgiving.
