I ordered a 2004 3500 quad-cab short bed pickup 4x4 with the 305 ho in auto from a dealer in Long Beach ca. It is to be built when the lines start back up in mexico due to the holidays which is this up comeing week. I asked about the new engine and the dealer said he knew nothing about it and it was'nt on his computer for ordering yet. I need to know if any one knows when the new engine will be up for ordering and if I should just wait for it or go ahead and take the vehicle i ordered ?.
