Under $4k budget build LA360 build

I just recently did a budget 400 build. "Somewhere" under 3K. I tried to get it under 2K but couldn't make it.

How? I haven’t fully run the numbers, but I was thinking $4k was a good number. Should I be shooting for $3k?!? There shouldn’t be much machine shop work as it was prepped by his local machine shop and was ready for a build before the PO went another route. It was stored covered in a climate controlled environment and looks legit through pictures. I hope that’s the case.
