Joea,
Here are some times that might help:
It took my machine shop about a week and a half to vat, inspect, and line bore my short block. The shop that machined my block did NOT turn and balance my crank. I sent it to another person who specializes in cranks. When I took my crank to my machinist I also included the pistons, rods, rings, harmonic balancer, flywheel and clutch for balancing. He had my crank and parts for about a week. In short, it took me about two weeks to get all my parts back to my house for assembly. This is the easy part but making sure all your gaps and torques are correct can make or break an engine. I failed to check my
oil pump flange that bolts to my block for uneveness and consequently it leaked at the gasket. The gap was very slight but it caused my
oil pressure to be significantly less than it should have been.
The point I am making is that everything has an order and is important and you really need a good manual to follow if you have never done this before. BUT, the grin on your face when you first fire your engine up would be a Mastercard Moment...Priceless!
Go for it! You can always rent tools and find help here.
