There is a lot of hard work shown in all of those pictures.
If someone can tell me somewhere I can host a movie file (.AVI), I would love to post a small clip of when we started the engine.
Dave, I believe I used a marine underwater epoxy to fill in around the oil dipstick. It was something that the old-school Pontiac engine builder I know recommended. I'll get the name of the product tonight when I see him.
