Well, I bought and brought it home a couple weeks ago. I have partially disassembled it. My findings so far...he used standard length push rods instead of the .100 longer ones that Procomp suggested. The crank has "INT 1900 grams" printed on it even though he insists that he bought an Ext crank.The mains look fine wth no copper showing or discoloration. I still have to take the rods and pistons out and then it will be totally apart. So far, I'm still puzzled. BUT the parts look great!
