It sounds like you were doing it as a sand casting. I wish I knew more about casting. Gotta hand it to you though. You deserve the Golden Wrench Award! For your Supracharged.com website and all your mad scientist Toyota engine swaps. I hope you will ask the casting company, that you use to make your bellhousings, to let you do an article on the process. Take lots of pictures and also fill us in on the methods you used to mock-up your plug. -- Matt
