Complaint Review: us engine production inc

 I bought a hummer h1 from a great dealer that had installed a updated 6.5 engine from us engine production I put on about 1000 miles and engine blew out fire ring on head gasket. After contacting dealer I purchased truck from they gave me the paperwork on engine I proceeded to contact Eddie from us engine production who gave me the run around about the warranty I had my mechanic remove the head to see what had happened he found that the pre-chamber cups hadn't been properly installed causing the failure. I took extensive photos and sent them to this Eddie who told me that it wasn't his engine and refused to warranty the engine even after I had the invoice with serieal number and had the dealer contact him he still refused to warranty engine. I am diffently contacting BBB and am in process of having to sue them to get this resolved so much for driving my new hummer any time soon. Stay away from this company extremely shady!!!!
