Bearings-100

Machine Shop- 40?! I think not my man.
He needs to regrind and polish his crank, if it's still useable after driving on it with knock. Don't forget he will need to have his crank balanced too. That alone is another 250+.
New Piston rings means rehoning the cylinder walls, decking the block etc if you are doing it right.

Not cheap.

Oh, and he needs a new rod.

Machine was $140.

No need to "deck" just bore check and honed.

Crank only needs to be balanced if it's machined, inspection is all he needs ATM.

Gasket kits can be had for $140ish, oem head gasket obviously.

Ive seen both OEM and ACL bearing sets go for around $100 for both rod and main.

At the end of the day it will cost $600-1000 depending how much he wants and does too it. However, he'll have a fresh motor with perfect compression and piece of mind.

Then again you can do all the work and cost to rip it out, swap a high-mileage KA, boost it, tune it... and hope it doesn't start to knock...
