[ERA 778]

I ordered my 427 in August 2008. I actually asked Peter to hold up on it for a while when the economy went south, but then they got right back on it when I called again. Delivered it end of April 2009. My was basic kit - I bonded the body myself, etc.
Peter had to ship a few of the parts later on, biggest delay was the Jag center section; I din't get it until mid-September.

So, best answer: Talk to Peter, tell him when you want it and how much you want them to do. He'll give you the best estimate for sure, but don't believe him! Add a couple of months at least.
