    1. factory 6 lug 14SF axles will swap into an 8 lug 9.5 14BSF without any modification besides brakes. Right?

    2. How hard is it to get a short bed 1/2ton Chevy 4x4 with a small block, either TH350, TH400, or SM465 with a 205, stock 1/2ton axles, 33" boggers, 15x12 Eaton steel bead locks down to or lower than 4,500 lbs? (Not removing outside body parts)

    well..for number 2..
    if you have a short bed 4wd chevrolet with a small block, auto, 33s and 15x12 wheels that weighs more than 4500lbs, you have a problem..my 86 long bed 4wd manual trans 350 on 33x12.50 wild countrys on 15x10 steels weighed 42xx..
    4119 is what my registration lists as the stock vehicle weight for my 1986 long bed..but that was with 235/75s and a v6..

    1. yes will swap, might even be able to use existing hose even, if not then swap it,

    2. light duty trucks are not as heavy as you think- from factory anyways,.

    Well I picked 4,500lbs because my blazer weighs 5,260 with me in it(no I'm not fat). I have 3/4ton running gear and I know the 14BFF and heavy boggers add a lot of weight but I have a a 700r4 and 241 behind my 406 which would be lighter than a 350 or 400 and 205 combo. I guess blazers are heavier than short beds then. Right? I want light as possible because I want to build a little short bed with 1/2ton axles(maybe a 14BSF if I break the rear), 33" boggers in the back/33"TSLSX's in the front, both on 15x12 bart steel bead locks and a built small block. This will be a little toy truck for mud racing and Pismo beach where lots of HP is your friend and shedding weight is like gaining HP. I want a cheap toy truck that I can use instead of my K5 because the K5 is getting nicer and nicer as more money goes into it and I don't wan't to tear up new paint and interior work especially when it's my DD and I can't afford to have it broke unlike another little truck.

    I am thinking of building a...
    short bed 4x4 1/2ton
    built 350SB making around 350HP especially into the 4500 to 5500RPM range
    undecided on tranny
    203,perferably a 205
    4" to 6" lift
    33x14 boggers in the back
    33x15.50 TSL SX's in front
    Bart steel 15x12 bead locks
    Semi gloss black back yard paint job to match wheels
    probably a swapped in 14SF if the 10 or 12 bolt doesn't last.

    Build a custom trugy. no body, all tube frame except for a firewall and floorpans. 2wd or 4wd. it's all your choice. You can go as mild or wild as you choose.

    Oh yeah, I forgot to add I want to keep this a TRUCK, I'm not a big fan of truggys in anything but rock crawling(no affence truggy guys) because I wan't it to look like a truck because short beds are so cool and I like a windshield and cab to keep the wind, sand, mud, any weather, etc, out of my eyes and face.

    Go run your truck onto some accurate scales and see what it really weighs. 4119 is for a base model 2WD long bed...

    The K5 might weigh 300-400 more than a short bed similarly equipped due to the hard top and tailgate...A stock 4wd short bed probably weighs 4700-5000 lbs.

    Thats what I was thinking and thought if I could get it down to 4500lbs total weight with the heavy swampers, that wouldn't be to bad.

    What are some good ways to loose weight, besides switching/removing body parts?

    Use a 350 or 700 with a 208. Probably won't break it with 33"s. That will save some weight. Plain jane shortbed. Manual everything but brakes and steering. No A/C. Aluminum wheels, heads, intake, radiator.

    Just a few ideas.

    I don't wan't aluminum heads because they are too expensive, definantly an aluminum intake, I wan't a 203 or 205... I wan't the taller geared low range because it will be a hill climber/sand/mud drag truck. Is a th350 heavier or lighter than an SM465?
    I was thinking take off the tailgate, inner rear fenders, gas tank and use an external small fuel cell, strip the interior, single muffler. /forums/images/graemlins/thinking.gif

    TH 350 is definitely lighter...prolly close to 80 lbs lighter, maybe more.

    Aluminum rims will help a little, so will rear disc's. Lightweight racing buckets will shave a few pounds too. Headers versus manifolds...should be an easy choice. Tailgate net versus tailgate.

    My longbox C30 weighs 4900 lbs with a full tank of gas and nothing else. Good luck getting a 4wd rig with an additional box and axle to shed weight.

    I estimate that my shortbed with 350/465/205 and 3/4 ton gear and 38s weighs 5000 at least, with the addition of 1 ton gear, its going to be more.

    5,200 is light for a Blazer.

    A shortbed truck is much lighter than a Blazer in stock form. In most cases a Blazer is heavier than a K10 longbox that is comparably built.

    i run a set of scales for a drag @ bogg racing series in michigan and most short box trucks weighed 4400 to 5000 pounds depending on what you want on your truck sounds like you are just going to wheel it then take every bracket of the frame your not useing lose the bumpers put in a plastic fuel cell no sway bar every little bit helps i have my 84 short box down to 4163 pounds with the fleet side box on i havent weighed it since the step side was put on but by this spring i will be around 3500 pounds with 350/350/208 combo 44/12bolt axles and 33 boggers i have a complete fiberglass front clip and doors and rear box stepside fenders going on it
    bad thing i have to go to 88-98 style cab pic of it starting the swap

    Thats exactly what I wan't. I was thinking a plastic fuel cell too, I have even have 33" boggers planned too! I would like it down around 4,000 to 4,200 lbs and I would be very happy! I wan't less weight mostly to help 1/2ton running gear last along with letting it be able to spin the tires easier and go faster.

    1. you can put the 6 lug axles into a similar year housing with no mods other than drums. If you put them in a housing from 81-87, you need to space out the backing plate 1/2 inch IIRC.
