I'm sure you guys get this question all the time, but I'm going to ask it anyway. How many of you have put a y block in a shoebox ford. I have 51 sedan with a locked up flathead. I just came across a y block that has 10000 miles on a rebuild and a 3 speed trans to boot for really really cheap! I'm thinking that this would make a great replacement for the old flathead, but I am scared that it will be too much of a job for me to swap this motor. I am pretty inexperienced. How hard is this one to pull off?
