Some have told me that cast aluminum would be the cheapest. Yes, but not before thousands of $$ in tooling, $35 or so in each casting, and then the price of fixtures for the CNC, design time for the CAD work, and actual machining. And this is going to be a low production item anyway, so that means these costs have to be absorbed from 100s of covers, not 1,000s of covers.

With the same reasoning as the cast approach being cheapest, you could argue that injection mold is even cheaper...but the costs of making the first cover would easily exceed the cost of making the first cast aluminum cover.

So...here we are with a billet timing cover. The cheapest approach by far. Even with the cover beginning as a 20 lb piece of billet. The final piece is slightly lighter than the GM cover.
