Re: moss engine "red"
Doc, check out the Craftsman version of the wrench. Not only are they US-made instead of Chinese / Taiwanese, but they have a locking flex head. VERY nice tool.
As for colors, remember one more thing. Unless you're going for a show win, the engine can be whatever color you like, just as the body can be. It's just paint and it will be painted again in the future. I don't like red engines in red cars, especially if th reds are different. If I had a red B, I'd personally choose another color, perhaps gray or Austin green.
