318 tear down... it’s about time.

im guessing it took a number 2 in cyl number 2 is why it was running so rough. my numbers matching motor looks like it was 6 inches deep in the dirt on an angle for 10 years so i am hoping that i can do what you are going to do to yours to mine.
I am copying a build a while back from hot rod magazine. Not going to reinvent the wheel here.

If you google “400hp 318 build”. You will find these exact same specs that I am using for my build.
