So I was browsing Craigslist found a guy selling a "Built GSR Block"
Here's what the ad says...it sounds good, but I'm unfamiliar with some of the brands he mentions, help? Suggestions on what to find out? Thank you!

B18C1 GSR block bored to 82.00 mm and had it decked
RS Machines 82.00mm PR3 pistsons 11.5:1
Block guard
New King Race Bearings/thust washers
Crank journals have been micropolished
Brand new Exedy lightweight flywheel
Brand new stage 2 6 puck clutch
Lightweight crank pulley
Rods have been reconditioned with ARP rod bolts
Entire rotating assembly has been balanced: pistons, rods, crank, flywheel and pressure plate
Brand new water pump
Comes complete with everything including the oil pan just bolt on a head and wire it up

 

Sounds fine. Make him drop the pan for you so you can make sure it has what he says

 

Receipts for machine work or walk away.

How are you going to know if its been honed?Micropolished? Have the bearings been sized properly?

If he claims he did it himself, walk away. Sizing bearings properly is extremely difficult unless you are meticulous and own some nice tools. Although some will argue that 'slapping bearings in' is fine, paying for a shortblock isn't worth it unless it was done right.

Good luck! I have heard of the brand 'king', I got a headgasket for my 89 DA, its holding up fine

 

Thank you both for the great advice! I will update if it works out!
