Hello, I am about to purchase my first Blazer. I have the opportunity to buy a 1974 with a rebuilt 350. Since I know little about the model in those years can anyone here tell me of any known issues with the 1972-1974 models and if any of those issues would make one want to favor the purchase of one over another? So far the only one I know of is that the 1974 is one year inside the California Smog requirement. They change it every few years so I would have to get it smogged. Other than that does anyone have any words of advice? Thanks! Jeff
