A 1988 Suburban, to be exact. 101k miles, 350 (5.7L) V8. Apparently it's an '88, but it's carb'd... which contradicts what Wikipedia says, as that in '86-'87 GM switched to the TBI?
Learn me about this generation of Suburbans! The interior in this one is immaculate, and the exterior has absolutely zero rust. MPGs are going to be bullocks, but if I can do a few things to squeeze out 3-4mpg that'd be great (The last thing that would make this truck PERFECT would be if it were the 6.2 Diesel!). I know for a fact that I will be upping the tire size 1-2 (but not raising the height) sizes - is the speedometer adjustable to compensate? I don't know what gears the rear end has and I don't know if it's the three or four speed transmission.
The A/C also doesn't work, which is rightfully so as I'd need to convert it to R134 anyway. How much would the conversion (compressor, lines, any other defunct part) run me if I did the work myself (minus evac/recharge)?
The motor definitely needs a full tune up (plugs, wires, cap, rotor, oil, filters... everything), and I'm even looking into seeing how much it would cost to swap in a 6.2 diesel. The car will be 25 years old, officially in January of 2013, so there will be no more emissions inspection for it. I'm thinking catless pipes with resonators? Helping the flow should help mileage 1 or 2, in addition to some headers. What about adjusting the timing with the addition to a higher octane? What about a whole new 350 TBI?
So... tell me, what are the good sides and bad sides to this generation of Suburban? What should I do to the motor knowing it's been sitting a while, besides the obvious tune up? What can I do to squeeze a few single-digit MPGs out of it? Or power, even? Rear end? What else should I do to this tank, while keeping in mind that it is going to be my hauler/grocery-getter/cruiser (GTI for all trips over 5 miles )?
Here's a few pictures for your troubles. I take delivery on Monday.
