I'm pickin up a GSR longblock this weekend w/ a fully rebuilt head, but the block has 100k, would you guys rebuild the block for good measure or if it looks decent throw it together and run it?

 

do a cylinder leak down test to ensure everything is sealing, and then rotate the crankshaft if there is no binding you should be pretty good. if you really want to get in there check the bearings for unusual wear.

 

I'd run it, but if your planning on leaving it in there for another 100k, i'd spend the extra $200 to have the block cleaned/honed, then throw some new rings, bearings, main seals, and oil pan gasket in.

i'd do that too its convenient

 

It's a lot easier to rebuild it out of the car than in the car.
