Well, I didn't take everyones advice, but it ended up working out. And, it's home and running! There are some bugs to work out still, but I can drive it. It went on its maiden voyage tonight, 15 miles in town and it did great! Temp held steady at 165*, never stalled or even bucked, and throttle response is good.
I need to get it in to have the A/C checked, put the front air dam back on, and get it to PDR to have a couple of dings (which may have been there) taken care of, going to order a new head unit/rear speakers and small powered sub.
Oh, and she is dirty. He said he doesn't like to wash customer cars so he doesn't scratch them. Fair enough. But he said he rinsed it off and let it dry. Would've rather have just left as it was, but I guess there was some effort. This weekend my plan is to clean and detail the truck and put some miles on it!
The main issue I'm going to ask for advice on right away is the belt slips/squeals. Anything over about 5-10% throttle and there's a constant squeal, it seems to be load and RPM dependant. It is there even when in park without load when revved, so I'm pretty sure it's the belt.
