i bought one for a project, then ending up getting a gm ls6, and i sold the block locally. The buyer had it checked by a machine shop and was told they wouldnt recommend any type of performance build. the liners for the cylinders shifted when the block was cast and then when the cylinders were bored, it left the cylinders walls very uneven. like to the point one side had a visual amount more sleeve material than the other side. like a 10 over bore would have been impossible even. I gave the buyer his money back and sent pics numerous times to TSP. they finally responded back with that they couldnt issue me another block cause they looked at all they had and they were like the one i sent a pic of, so they arranged for UPS to pick it up. A few weeks later i FINALLY recieved my credit from them.
