What to do with a junk 400 block??? (Creativity is a +)

Use it to make a mock up 400 block... ever wish you had a fiberglass/foam mock engine. brush it down with axle lube and do one side at a time using fiberglass then let dry, remove the glass mold from the 2 sides (front and drivers side and rear and passenger side) 2 piece...
The inside will be a perfect mold to poor a cast inside of.
Have you ever priced a plastic/foam moc up 400 c.i. block :coffee2:

counter weight for a catapult :D Put in in a near by pond and catch fish around it :laughing: Dig a hole and plant a tree next to it and watch how well
the tree will grow with the added Iron :happy1:
