Here is a picture of the piston when it broke. Look how small the ringland is where the valve relief is cut. It is a weak link for sure. Like Ed mentioned. It is a 1 size fits all engine for all applications. I would look into the Gibtec pistons and build a shortblock with those. It is a little more work, but the quality and piece of mind is well worth it." </p><p></p><p><img src="https://lh3.googleusercontent.com/hN2sPASXtsZBCA_buzrDhURRkHYhxVLZctJeuhLyq7LhWMIIrboIYR3MpN8dihcEIHK1xB8d4v6aXkZTPQGOdlUX5WoHUtp2_KCZ295LXDcX80HT3ARmI1ruTXS7PPSns-H5TCiNmCE5eAoOWLWr3KhrOpks7pDxHtEiQPTJOJAKpnQU_oBnogJREHvIanLENkn5aff1OuGIfWO5D358kZLD_DI6cAubWtzpQX_JQGRffPbeZ8YhER_nRpZh4X5j9JT5RE0Iinmoh6bzNQIyyGUEGwF7nupSyF0uU-q6ocM4GjWgbl2HSYjAa7K0M--nBZOPqN-6GCayQAq2KYk_fZUWMV_03dBRVEd9ei0kktg7BJREYjA7gMHEXeV5PJsNZqzAOi7Il8dsFAdxFlpnoBWQ2Zu5B_xT48mwsR0UUR7NgAnDk8MoYBxPZMCbFZd1bdl4fphN5uKHjPwXKsPWkEd292Q_0S9ThxTUI_QEveP9gHSGdzbJ7eP53eFvR9yTw5qyDSo0UHF3W2-Xj2Lrivm4WirDQfNrZz1WfUUxf0sgufF5BrLoxjKtb7JxOlagvPg1n3z4UODSSbOS8wE9c7qSfGLxMqE=w1254-h705-no" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="https://lh3.googleusercontent.com/yuOwoLM3eBa00JBKcu1WsxBSgV-mdqCY1ef3zkdRpipI7N85isbKbuhqaIAiWRSjM4Ey9XAVevjd3ARN1fgorKiWIycVJUkq618A_gXZOgwqHaO8fWK_ATT9GBFaQQWGJCvPBApNmr3iSWOjBvhJe2xH4rdWc3qbmxQ9fb76cSS8uoYDSDAI9gLtS4m-lgxsxi1lT7IvcwmDRnNeLBa9tKaZLPKxN0QSkjf5ydwdFMunSrafmERmBdHoyFTozUD5Il1ioO7eCMXloOypKAQ4rh24RtKWmH53skQOybDPRkeAk8Be2IQ-Sauzg8RVpiZQU4MdeJ8rIQFz2Kjd2hKz2KCRDiSQThvvsoSfSXyt1o7_b3aaOiSCDhj6SrERAdTyjXAvvA8OE6ZTJ1zaDnsQS1vz8zTTF4J52LEWjMuH0gpfnvhDuiaVQTsPtsqmXIP8G1jJ3PtxfEpkd1uHlng-talEcdHTu5h9BSzbtX2jxz6PCnQJnH5Ld4KQJcE3vrjV5KC7F2goRc3JGIfszkqcIrVd0eeucR7gtsjYEGfpaHXK9NX833D-O-sLs6Gp1aUJVsNLlr9tjbzU8o17b2rC9LA8UNWN5Zk=w1254-h705-no" alt="" class="fr-fic fr-dii fr-draggable " style="" /> When we got it back, the reliefs were on the wrong side.

[QUOTE="Juiced46, post: 15327342, member: 11519"] I am going to copy and paste what I posted from the other site so the info is on both. Like I mentioned in the below quote, the pistons are the weak link. The ringland where the valve relief is cut into is very very thin. If this shortblock came with a better suited piston it would be a much better buy. You are better off building one with better internals for roughly the same cost. "Ken, I would explore other options. I had some issues with FRPPs 5.0 shortblock which looks to use the same exact piston as this 5.3L. The pistons are very thin on the top ringland where they cut the valve relief into it. It is only about .090" thick in that spot. On a 500rwhp Procharged Mach1 I installed this engine in, it broke the ringland clean off on the very first dyno pull. Ford was good at honoring their warranty and paid to have it sent back to them, fixed it and sent it back on their dime. They covered a portion of the labor. When we got the engine back, they installed all of the pistons backwards. The valve reliefs should be on the exhaust side, they were all on the intake side. Also, Ford does not build these engines, they have them built by an engine shop somewhere in Michigan.
