Here are the engine parts at present. These all appear ready to go for the final model.
If a couple of years from now anyone here is into 3d printing, these would be the parts you print from the giant collection of STL files that will comprise the 68 GTO model.
One thing cool about the model files, you can easily scale them up and down to print the model any size you want, well any practical size, so like from 1/24th to maybe three feet long for the whole car.
