    mods for LONG LIFE (ie a rustfree chassis for decades??)

    Could you educate me about both? Especially any references for the latter (if it's something from the factory, NOT some "dealer option" thats as phony as some of the undercoatings that made things rust faster and such I used to hear about but genuine factory backed with references "yes this...

    Coefficient of drag??

    Probably a wierd question for something so bricklike BUT i'm wondering if anyone has ever heard a figure, ever, or even an idea of what it might be. :) I read somewhere that the square body was actually one of the first intentionally aerodynamic pickup designs, possibly assisted by computers...

    list of axle ratio options? (esp in 3/4 and 1 ton)

    I'm curious what is out there for swapping options... I'm aware there were GM 12 bolts with all the way to 2.29 ratios, even in the pickup trucks I *think* for the 1/2 ton, but i'm especially curious if there were any 2-series ratios available in 3/4 ton or 1 ton axles especially in 4x4...

    88-91 Suburban welcome here? Differences?

    Well I was sort of hoping for more than 'just power mirrors' as information, yes. :) Usually later years have problems solved that earlier ones don't so i'm probably going to aim for a 1991 Suburban 3/4 ton (or possibly even 1 ton if one was made) then as an acquisition goal. I'm still...

    mods for LONG LIFE (ie a rustfree chassis for decades??)

    Imprecise language makes things sound too wishful. :) Let's try again. 1) Spend the least I have to to get the job done. The same as any class 8 trucker is trying to do, who routinely drive vehicles designed to last a million miles but are often forced to upgrade to gain 1/2 an MPG or to...

    mods for LONG LIFE (ie a rustfree chassis for decades??)

    I posted my introductory post if you want to read it http://www.gmsquarebody.com/forum/showthread.php?p=236154#post236154 but the super-brief version is that I hope to rebuild a truck or/and Suburban to literally last for decades/the rest of my natural life. Maybe I just don't like change, or...

    Hi i'm new here - previous SB owner wants to be again

    Howdy, actually my third post because first two were off the top of my head questions of specific information I was looking for. If anyone wants to suggest other great sites for discussing these trucks (either in combination with other trucks, or other GM, or just these models) please share...

    IH DT360/DT466 feasibility?

    Has anyone ever done this swap or looked into the feasibility of it? The international harvester 'DT' (and later HT) lines of engines, most commonly seen in school busses and medium duties, most commonly in sizes of 360 or 466 CID although other sizes exist. What I can find about this engine...

    88-91 Suburban welcome here? Differences?

    Just curious on something... i'm aware this is sorta 73-87 'square bodies' but they used the same chassis (with a new grille) on the suburbans up until 1991 according to every reference I can find. :) I'm just curious what notable differences there are vs a 1987 model if anyone knows...
