Re: gas mileage?

if you have to ask, then 10-mpg might not be what your looking for. But who cares about gas when you driving a real truck [img]/forums/images/graemlins/usaflag.gif[/img][img]/forums/images/graemlins/k5.gif[/img], and the guy at your local gas station will know you by your first name...

Re: gas mileage?

10 MPG sounds about right for a stock truck. My truck, with a mild build 350/TH350 on 35" tires gets in the 6-8 range. I can't tell exactly because the speedo is way off. There is someone who said he was getting in the 14mgp range but I think he has TPI.

I get about 12, with a mild built 350/350 auto. 33's and 3.07 gears. I used GPS track log to get my miles, so I feel it's pretty close [img]/forums/images/graemlins/k5.gif[/img]

Re: gas mileage?

I get 11.6 with a 350/350 engine tranny combo. There are a lot of things that could add up to better milage but they would also add up to a worse truck.
Be warned- gas tanks in these blazers are way too small.

Re: gas mileage?

I think that the question of gas mileage is a hard one, because I get about 10 mpg my blazer. With a 427/TH350/NP205, with 4.56 gears w/ 40in. tires. [img]/forums/images/graemlins/k5.gif[/img]

Re: gas mileage?

If it is in good shape, $1500 sounds like a fair price. Make sure that the rocker boxes are not rusted (large boxes under the front floor boards between the rocker panels and the frame). Windshield frames can be hard to fix and harder to find replacements.

Re: gas mileage?

i was wondering on what size tires could fit on a blazer stock? how much would a lift cost for one and what are some good brands of lift to install. i am looking for a 4" lift and what size tires would fit? my friend has a blazer with 4" and fits 39.5 boggers with fender trimming. thanks for all the info.

Re: gas mileage?

You might be able to fit 33's stock. If you trim you will have no problem at all.
Most people run 35's with a 4" lift and don't rub (or not bad if they do). I've got 4" lift and run 36's with the rear axle moved back 1", minor trimming in the front and more then minor trimming in the front. The reason I only needed minor trimming in the front is because I have no flex up there because of the Rancho springs (too stiff). I don't know that I would go above 38" with only a 4" lift.

Cost to lift will run from $300 up to a few thousand if you do it right.
