    Hey everyone, my first post, I have been looking for a blazer for a few weeks and have it down to two trucks.

    One is an 85' Blazer
    -New 350, tans, shift kit (8k miles on the new stuff, 140k on everything else), new interior, 4' procomp lift, 33' tires, aburn gears 3.56 (I think).
    $7400

    Second is a 90' GMC Jimmy
    -6.2L Diesel, Banks turbo, 96k miles, no lift, new 31' tires.
    $6900

    Both of them are in near perfect condition, both drive great, both have stock axels. The price difference is not a big deal. Are there any big pros/cons to either the year or engine type ect..? Which one should I buy??????????????
    Any oppions would be helpfull!! Tks

    do you have any maintence records on the 6.2? Do they have reciepts from the gas powered vehicle? how do the bodies and interiors compare? Personally i would go with the 6.2.

    I agree with rugger03. I am still learning about them, but I would go with the 6.2. I love mine and the mpg is good to. There is a lot of people on here that know what they are doing. They helped me out so much!!

    Take care Mike

    The 85' (gas powered) has all the receipts, the 90' (diesel) has no receipts, the current owner has had it for 3 months and knows nothing about cars, but it has a clean carfax report. The bodies are both fantastic, the interior on the 85' is a little nicer (new carpets and dash) but their both in excelent condition.

    I vote for the 6.2, newer, better economy (over 20 mpg), turbo is good, not lifted so less chance of offroad "wear & tear", diesel is probably not as hard to emissions test, no carb, no electronic engine controls. The 85 is carburated and subject to possible emmisions problems.

    I own one of each now, diesel and 350. If you plan on driving this truck a lot I would go diesel. With the banks turbo the 6.2 will keep up with a gasser and prob tow better. Diesel will prob pull 20+MPG compared to 9-12 on the gas. My two cents. Good luck,
    Mike

    Go with the 6.2
    Diesel is hard core.

    I just got a 6.2 Jimmy, and it's the BEST. I've been driving around for 5 days on a 10th of a tank and the guage has hardly moved. And EVERYBODY looks when they hear it coming. Mine isn't turbo and it's got plenty of power, but someday I will get the turbo. I suggest you do what I'm doing and change ALL the Fluids and Filters (there's a bunch of them) right away, then there's no doubts.
    But that's just my opinion, and you know what they say about opinions...

    Thanks everyone, your posts help me make up my mind! I bought the 90' GMC Jimmy (6.2L) this morning. I'll get some photos posted up soon, and I'm sure I'll have a million questions.

    Way to go! I wish I could have found my suburban with a 6.2 in it.

    Wow I'm suprised to hear all the support for the 6.2. Don't get me wrong, I drive an `83 Jimmy with a 6.5 with all the 6.2 injection system, but I get nothing but "stink face" when I tell people I have a pre-duramax GM deisel? I have had nothing but happiness BTW, just thought I was a lucky one.

    I always though the diesel were undesirable.
    This kid that is going to my school is trying to get rid of his clean 85 for like 2 grand. People here just dont want diesels i guess

    What in the hell are you thinking?! You bought a diesel? Lol, only kidding /forums/images/icons/smirk.gif . Getting a diesel really opens to the door to even more alternative fuels. You can even run the darn thing off vegetable oil if you wanted to. There was quite a long post on the topic about a month ago. I'd be interested to know how much the banks turbo helps. You can tell all the dodge guys nice cummins m'am, but I have a detroit desiel. If you're talking big rigs I like the Detroit better than the Cummins, but lets not being comparing it against a Cat motor /forums/images/icons/wink.gif .

    I love GM, and I love Diesel, but I'd never combine the two, that's for sure.

    Gutless is an understatement but at least they're dependable.
