How many assemble their engines

I always do as much as I can myself. To me , it's the most fun part of the car build. Besides the insurance that it was done correctly. I have used several different Machine shops over the years. Some are better than others. I've had issues with a few of them, but I'm pretty picky.

That first motor, what is that? Size i mean? Looks like a 440 but????? Looks mean nothing on the outside!:D
