No need to scale anything down. Just wanted to let people know what to expect. I've got the bottom end done. I noticed that the cap screw heads for the conn rod ends are rubbing against the block. So I had to pull the old dremel out and take some material off the block where the cap rubs. I also had to take sand down and file the timing gears to ensure smoothness. Same thing with the piston and walls. Sanded those down too to open up the tolerance. The tolerances are pretty tight which I like, but my makerbot 2x isn't producing products that are as tight on tolerance. Now that the bottom half is done, I have to sell well done! I love it. I'm printing the ported head now. Look forward to it!
