the 4.3 will NOT give you better mileage, unless your doing highway driving. i have the 4.3 in my truck, and i get worse mileage than my dads 02 tahoe with the 5.3. my truck is the baseline and weighs probally 1500lbs less than the tahoe. if you want gas mileage, cheap and reliable, get a used highmileage honda. although, the 4.3s are woken up with a few basic bolt ons and tune, you will still be dissapointed unless you put a blower on it. with just a vette servo in my trans in my ecsb, on blacktop i can bark the tires really hard when i do a 30 roll, and then when i shift.

FYI my 04 silverado BRAND NEW with a 4.8L and a 5 speed - full power everything, cd player, air, carpet, etc. was only $15,800. That was with 6 miles 
On a 2nd note, I also have a 4.3L 5 speed RCSB truck that used to get 16.9MPG all day long no matter how you drove it. Cold, warm, highway, in town. Didn't matter, it was always the same mileage. UNTIL for some reason when the truck got around 110K miles on it, it started getting better. I verified this with my GPS even since I was in disbelief. It went to the point that I now get 21-22 mpg doing the same driving in the same weather. It's just weird. Whatever though, I love my 4.3L. Tons of low end power for any job a 1/2 ton truck needs to do. Smooth and cheap to maintain. I say go for it.

Good grief man. Buy my daily driver. It gets 15.5 mpg on my daily commute of city/hwy mix.
