Yea, Denver Metro area sucks, every vehicle newer than I think it was either 1952 or 59(cant remember) has to have an emissions test, granted it's not as stringent as 81 and newer vehicles, but stills SUCKS! I'm not exactly sure what cam is in it, but it sure pulls hard from about 2800-redline. The shop I have it in is a pretty respected Z-Car shop for the Denver area, and the owner who is working on it supposedly knows his stuff. Part of the problem I guess is that it has the triple Webber setup, and I hear they are a pain the in butt to get dialed in especially in this altitude. I'm just getting bummed because I'm losing the rest of my summer, and I haven't even had a whole lot of time to drive my new ride! I'm also kind of worried to see the final bill, I appreciate the knowledge of the 4 hours or less, I'll definitely keep that in mind.
