    What have you done to your square lately??

    Started placing the 3" exahust back into place (has smitty mufflers attached to them) on each side of the truck. Dumped pipes out before rear tires (and left room between pipes & gas tanks), will maybe trim them up after new rims/tires are installed if I don't like how it looks.

    Installed headers, and started working on exhaust system.... THEN>.....did some brake work, and a while later I really wanted to start swearing......puddle under booster, and pass side caliper leaking... (I started a thread on this bs going on...

    Advice on: Master cylinder, booster, and calipers (leaks on 76 GMC 1 ton--pictures)

    Hey gents, I was hoping not to spend a ton of money here (I am so far over budget right now I am cringing and not even close to done), but being as how I have NOT worked with squares until this point, maybe you guys can give me some advice. Advice I am looking for; 1.) Would you use a...

    Dually Wheel Fitment Help

    Hey gents, so what you are basically summing up is the 14-bolt corporate rearend is the one that would work well in the OP's truck for a bit of fender clearance? I saw @Android04 original post in this thread and thought "oh $h!t, are you fugging kidding me"......granted my ride does not have...

    Rear axle: Welding on saddles at proper angle (due to lowering kit)

    It is leaf springs, brand new ones in fact. Not exactly sure how I could get it to squat, I have a feeling unless I put some extreme trailer to this thing it is not going to move much at all.

    Rear axle: Welding on saddles at proper angle (due to lowering kit)

    Ok, I see what you are saying, makes sense. I have the truck sitting on blocks right now, with tire pressures the same. No other weight on the suspension besides misc. stuff in the box, so the truck is sitting at it's normal ride height right now.

    Rear axle: Welding on saddles at proper angle (due to lowering kit)

    @Bextreme04 I actually do have that calculator :D Just now I went out and verified all my numbers, and here is what it is. As for the next step, should I adjust the rear-end up 10 degrees (to put it at actual 0) so it matches the transmission & 1st driveshaft? Shit, I goofed....updated...

    Rear axle: Welding on saddles at proper angle (due to lowering kit)

    @Turbo4whl @Big Chip I have read, and re-read this thread a lot here and posted my above message. However, after trying to process this info, and what you stated Turbo (post #18 above), if I understand this correctly what I should really do is remove the rear driveshaft. Then, measure the...

    Rear axle: Welding on saddles at proper angle (due to lowering kit)

    Ok, so now I am back at this once again. I have the truck blocked up on all 4 corners under the tires. Tire pressures all the same. My first driveshaft (from transmission) measures at +5 degrees (going downward). 2nd driveshaft measures at +1.5 degrees (downward), and the rear end is coming in...

    455 Olds not lining up well in 76 GMC crew....

    Thanks Dave, that makes perfect sense and is exactly what I was thinking in my mind after reading through these posts! Something will work, I just need to spend time on it! It has been a crazy busy summer with kids activities and whatnot, so not much time for the truck! Thanks again for the...

    Advice on Muffler Replacement

    @DoubleDingo and @Catbox I actually got a sweet custom set of shorty headers for this 455 (exact exit position as stock manifolds), and a pair of 3" electric cutouts. So, with that being said this truck already had long ass smitty brand mufflers on it, so I want to see what they sound like...

    455 Olds not lining up well in 76 GMC crew....

    That would be correct, and what I have been searching for is the 350 Olds Diesel mounts that were in the GM trucks, 78 to 82 or something?? Anyhow, it would have been a drop in. Granted with my adapter plate I may have had to make a minor tweak such as drilling holes in a different spot, but not...

    455 Olds not lining up well in 76 GMC crew....

    @Raider L I bought these frame to engine mounts from Summit, maybe I should've gone with a clamshell style??... I think as another person mentioned I will just get the mounts off the engine, bolt up the trans and then see what I have to work with. I also like the idea that @75Monza threw out...

    455 Olds not lining up well in 76 GMC crew....

    @cstew47 I too love the Oldsmobile's! Their engines have such a distinct sound. Even my 80 Olds 2-door 88 I used to own with the 307 & dual exhaust had a grumble of its own. A better grumble after I threw in a rebuilt 350 Olds Rocket. I found this truck with no engine, and I had this 455...

    Ok so posting by smart phone/dumb user sucks....I had a double post, so had to edit this one with some BS :D

    @bucket what I meant was 6 inches down to line up trans...I should have mentioned that.

    455 Olds not lining up well in 76 GMC crew....

    @Blue Ox unfortunately even a BPO trans would not help this situation as the trans would still be sitting in the same spot. I though the same too as I do have a long shaft Olds 400 that needs to be rebuilt. @Turbo4whl Yes I can move the engine back further, and the trans is bolted to the...

    455 Olds not lining up well in 76 GMC crew....

    Hey there gent's, I need some advice on this here issue. I finally got to the point of dropping in the engine to see what needs to be done to get it mounted up. I bought some frame to engine mounts from summit racing that looked like they "should" work, this was just a shot in the dark. As...

    '76 GMC 1 ton (454) radiator???

    What modifications did you have to do on the upper/lower radiator mounts? I am not too concerned about modifying things within reason. My entire engine bay is still open with no engine, so I have plenty of room to make things right the first time. I would rather put some sweat labor into...

    '76 GMC 1 ton (454) radiator???

    Well I am to the point now I need to get one of these here and I took your advice and I gave a shout to the local yard I buy a lot of stuff from, they have a nice 4-core radiator from a '97 3/4 ton Chevy truck. They also have a 2009 Silverado dual electric fan too, he said one fan has 5 blades...

    What have you done to your square lately??

    My dear friend, it is called OCVSD....obsessive compulsive vintage snowmobile disorder. It all started as a kid, riding with dad on his 71 Polaris, at 8 he bought me one just like his for $50. I have his, my grandmother's (his mom), mine my dad got me and a SnoJet like my mom drove when I...
