Thanks Guys. I like to ask things I don't know before I make an expensive blunder.
I finally have an engine. I built it with my dad, it was the first engine for both of us. Soon it will be in the truck... By soon I mean next time I visit and can work on it. Once the motor is in I can take it home and work more regularly. Here are a few pictures.
I wanted to leave the heads raw aluminum but the marks from past corrosion looked bad so I painted them silver. They look nice.
Then I put it together
Then I just layed the intake on. Its only in primer right now. It will be gloss black.
