5.0L Mercruiser Engine
I’ve posted 34 more themes that came in before last night’s deadline (including Jeffersonian from one of Prolific .71514 driver - Prolific). There are still a few more themes that may be added as they received in time bit were sent back to the theme author for one reason or another.
I also have about 20-25 theme updates that need to be applied and posted before any judging can occur. Unfortunately, the updates are going to have to wait for another day - getting the new themes fixed and posted took about 6 hours today. 
My sincere thanks to everyone who entered a theme and helped spread the word about the competition - 139 themes is more than I ever expected!
