The crank does show discoloration, but most used cranks tend to have this.
The main bearing measured out at 59.94 +/- .02mm
The rod journals measured out at 44.94 +/- .02mm
Both are not out of round and crank is true. The journals are also not scared. The front and rear main seal surface does show signs of wear but this is normal. There are no major flaws making this setup fail. Parts do need cleaned and and resembled, photos were taken as i took them out of the block. Looks as you could still polish up the bearings (optional) and have plenty meat left to use standard bearings.
The pistons show no signs of detonation or side skirt wear or excessive pin play. These parts are out of a 2.8 aluminum block that overheated and the head bolts pulled out the threads.
Thank you,
