All should know I have a penchant for breaking things, and I so happen to have a broken motor sitting in my garage.
I've bought a motor to run in my car, but while I pay that and recover financially, I want to rebuild this thing.
That said, I've done a ton of research but am a bit lost as to where to start with this:
I'm not sure of the machining requirements, but hopefully can find a reasonable machine shop in AZ that would do an inspection and cleaning. I'm not sure if I really need to go overbore on this as the walls look pretty great, some very minimal vertical scuffing but nothing I feel with fingernails, and the crosshatching still very nice looking. If I can avoid an overbore, I avoid the risks inherent with not being able to match the OEM's roundness tolerance / have the right torque plates, etc. Once its a shortblock ready for the top end, I have full confidence in my ability to set it up correctly, measure breakaway, install, etc.
My uneducated guess on machine work:
I'll attach detailed pictures shortly to see if anyone agrees with my reasoning or can help guide towards an excellent route to having this thing back together.

That said, I've done a ton of research but am a bit lost as to where to start with this:
- I have a used gen2 aluminator shortblock that has to have the crank replaced (and likely the pistons from p2v contact)
- I have a used crankshaft sitting here
- I will eventually have dollars to vaporize
- I can turn a wrench
- I cannot make machinist quality determinations, but I can dumbly measure things

My uneducated guess on machine work:
- Crank - clean + polish
- Rods - clean + inspect
- Engine Block - clean + magnaflux + finish hone + measure bores (before+after) + deburr
- Procure new pistons, rings, rod and main bearings based on above measuring
- Assembly labor - sizing bearings, balancing rotating assembly, install of bearings, file-fit rings, install pistons/rods
