91 4.3 FI, 700 R4 tranny plain jane 4 door 4wd Blazer. Price is right and it's in decent enough shape. Fuel economy is unimportant, but interesting, what can I expect? A very minor puff of smoke on start up..... might that be the valve seals? If my wife will drive it I'd like a 4x4 again, was this a decent model?
