Update on the 428. since I started reading the book How to Build Max Performance Fords FE Engines it's open my eyes to a lot of work I have in front of me and getting me excited. But when I went to work on the motor and try and find out for sure what I have I find out it was used for irrigation and this thing is froze up starting to get disappointed and wondering if it's going to be worth it because of how rough it is. I really want to do the build but looking at after market blocks that route is starting to look like maybe the way to go. Any good advice?
