I would recommend changing your pistons over to the forged pistons while u do have your block open allready. Unless your planning on staying on stock turbo. Then ur block should be reliable up to 450. What are your power goals? What size turbo? ECU? Also a mob list helps determine as well...U got a really good deal on the block tho.

 

If you stated the year accurately, it would have to be an EDM / JDM block -- what is it stamped?
