Chevy Camaro LS3 V8 Engine - Scale Working Model.
a few hours of printing.
Looks good. Am thinking of doing this project so Jr. can get an idea of how an engine is built and functions. It’s a far cry from when I was a kid and took shop class where I stripped an engine to the block and then reassembled. I guess their version of a shop class will be to rewind a DC motor? 
Can you make me one @Tim_Sills
