Thanks, Ray:
The motor is from a "Galaxie Limited" 1948 Chevy. Here's a link:
http://galaxielimited.com/EDIT: I had the wrong web address. The correct one is now listed aboveThere are straight-sixes in several other 1/25th-scale model car kits out there, but this is one of the best.
While I'm here, here's the latest update.

The hood was formed from a piece of thin aluminum flashing. I made a buck to shape it over, but the
aluminum would spring back when it was pressed over the buck....

I could have hammered it into shape on the buck but then I would've had to fill & file the
surface to get it smooth again (too much work). Since this was such a simple shape, I ended
up just rolling it with an X-acto handle.....

.....and using the buck as a test-fit guide.
Next up: Steering column & linkage. Stay tuned!
