We don't offer that service, sorry. Without us sourcing the parts and inspecting the machine work, we can't guarantee it is right. We use to build motors with "I found these parts" but those days are long gone. So are the days of us using OEM internals.
I am sorry it was a bit confusing as to what I wrote. We only offer this as a package, as shortblocks are VERY labor intensive. We have been sourcing the parts for a long time, and we know what does and doesn't work. I know who to get pistons from, and what time of year to order them. I know who is going to be my best source on rods and bearings. I have this all in order, so I can get parts year round. I can sell your the parts individually if you'd like to have someone else build the motor that isn't a problem.
Our average 4 cylinder shortblock ends up with something like 40 hours into it by the time its done. So...I guess labor could be $3230 (40 hours x $80.75, which is the dsmstyle.com discount) if you want to just bring in parts.

Otherwise, our shortblocks start at $2700 w/good core.
-Weisco pistons .020" usually
-Eagle rods
-King bearings
-balanced rotating assembly to 2 grams from accessory pully to flywheel/clutch
-all machine work done. (line honed, and bored with torque plate, all surfaces inspected and machined).
-boiled block
-needled block
-painted and spec'd block
-ready for head and accessories
-new oil pump/front case (installed).
-mirage stub shaft balance shaft "elim"

All you would need to do is put on your oil pan, your filter "housing", and all accessories (including timing belt stuff). Then add a head and away you go.

+$100 for the turned down balance shaft and a perfect balance. (Stage II).

The average core is around $200ish. This is a complete block (block and caps) and good crank. If you want the assembly balanced fully, bring in your crank pully as well as your timing belt cog and your flywheel/clutch.

So in a nutshell, we offer the shortblocks cheap because we have a system that we like and works. Whenever we have to get out of our "shell" for them, the costs go up 10 fold.
