Frustrated, discouraged and don't know what to do

[derotoreut]

OK I'm at this point where I'm totally lost and don't know what to do any more. Last summer I had a 383 stroker engine built by United Racing Engines out of Phoenix. After installing the engine I found out I had a noise that I couldn't identify. After trying everything under the sun, (and I mean everything) I couldn't identify the noise. All this time I kept URE in the loop on what was being tried. Unfortunately, no luck. URE suggested that I pull the engine and send it back to them to go over and rebuild as need be. By the way... through all of this they have been great. Anyway, they totally rebuilt the engine and returned it to me just before Christmas. Now after installing the engine I found out again that I have this same unidentifiable noise. After everything I tried I thought this noise was coming from the engine. I was so excited to get this reinstalled just to find out I have the same problem. Now I'm not sure if the noise is coming from the engine or somewhere else. I have no clue what to do any more. I thought I did everything I could the first time. I've had it.
