I wouldn't worry too much about the smog stuff. Its a lot easier to find smog stuff/work on smog stuff on domestic engines than it is our toyotas. It's not as big of a hassle, in my experience.
Yeah I was thinking about talking to you. I just remember when I was in the market for a yota, everyone told me to stay away from NV rigs because of smog. I wasn't sure if this was going to be a big problem with a chevy 350. I have found some good deals in the Reno area and I just didn't want to spend a bunch of money only to find I had to modify and change a bunch of stuff to get it to pass.
