> so i’m looking into buying a gsr block and the guys says it has aftermarket sleeeves. he thinks they’re dartons but can’t be positive because the block has been sold so many times since they were installed. is there any way to tell for sure if they are darton sleeves? he said he took it to a machine shop and they said they were dartons.

if he is not sure i wouldnt buy the block. There are issues with getting the sleeves to seal and if its been sold so many times they arent sure what they are you dont want to mess with it sounds kinda weird you know? If you are trying to make your horsepower goals you need to be sure of the parts you are buying and there is no cheap way to make horsepower. Buy a GSR bottom end and get it sleeved yourself that way you are sure of everything and if the sleeves sink you will get taken care of by the person that sleeved it rahter than dealing with a block that been whored out to who knows who and dont even know the brand thats just lame.
