Brian,
3700 degree days is about the same as the Russian River according to a viticulture book I own. Yes it will raisin like any black grape in a hot dry climate, but Pinot will be scalded to death much sooner.
I personally believe fine wines ONLY come from cool climates. I don't like wines to taste like black cherry cough syrup or Dr. Pepper, and that is what a hot climate usually produces. If I were trying to grow grapes in New Mexico, I would plant at high elevations. The cooler temps and bright sun would then give me a small chance of making something fine.
We grow Pinot in SW Michigan. It always attains 23 bix even in cool years and retains its vital acidity. My site gets 3000 heat units per growing season. My neighbor grows Syrah. It makes a lovely perfumed black wine here, but usually only gets to 21 brix. In that context, I recommended Syrah.
