Still an ok pump but not a big dollar pump. A 180 will bring the most and 215s are right behind them. Mileage and condition of the pump are a part of the price too.

The engine has 246k miles on it. How do I check to see what pump it is and what kind of price should I ask, if it is a 160, for it when I go to sell it?

Now that I have put a few hundred miles on it, I think that when I have it in the Suburban I actually may want more power out of it, So far I have only gotten about 15 lbs of boost going up a steep hill full throttle. Is that the maximum boost I should expect, or am I just not going to get more because I am not loaded enough?
It also smokes a little once it is "hot" at idle. What could that mean? it is a white smoke.
