If you've got solid experience in engine building, figure around the same it would cost you to buy one from a reputable shop. Maybe a couple hundred $ less, but that's about it. Unless you own or have free access to a machine shop, that is. What you save in labor, you end up spending on precision tools like micrometers, super-accurate torque wrench, angle-torque gauge, etc.
If you've got no experience or training in engine building, figure about 2x what it would cost you to buy one from a reputable shop. The first round of $$ goes into the engine that blows up first startup, the second round of $ goes to the shop you buy an assembled engine from afterward.
So...just price out an assembled short or long block from a few sponsors and plan accordingly. Unless you already own all the precision tools, training or supervised experience, there's no money to be saved on DIY engine building.
