    Crewcab with an I6. Hmmmm

    What the? A one ton with a gasser inline 6, with a 3 speed. That doesn't make sense to me. Did GM even make such a truck?

    Buss Bar?

    Here is another thread, with awesome wiring diagrams that I have used over, and over, and over....and over :Big Laugh: Scroll down & there are the '81 to '87 diagrams too. These were a huge help when tracing wires & fixing many years of other peoples messes on my truck...

    I think I may have bent push rods--and other issues (76 GMC W/455 Olds). Crap.

    I hear you there. Not a fun place to be in, but at the same token it isn't all that bad either as I am glad I did not find shavings. Your last statement is also what I was thinking too, just run it and keep an eye on it. Yanking valve covers to check rockers/pushrods is nothing. Back when I...

    Buss Bar?

    Your first post I see! Welcome, I've been through Vernon a few times, not too far from where I am up in West Concord. Not sure how different the years of trucks are, but I have a 1976 GMC truck I have been using for parts. Unsure if anything from there would be of help on your 81..?? I should be...

    To everyone questioning why I did not prime the engine, see the below PDF, step #9; https://www.compcams.com/pub/media/productattach/1/4/145.pdf Everything I did is exactly to what they stated. Remember, I oiled & assembly lubed the living sh!t out of everything, I was not concerned about not...

    I think I may have bent push rods--and other issues (76 GMC W/455 Olds). Crap.

    Ok, so I feel now I can rest a bit easier. I cut the filter pleats out carefully with a razor blade, got my bright light on each crease, the shines I did see were tiny, and looked to be common wear/break-in type stuff. No chunks (except some black carbon I was able to break up in my fingers)...

    I think I may have bent push rods--and other issues (76 GMC W/455 Olds). Crap.

    Here are some pictures. I tried my best to get a clear picture of this. I used my friends oil filter cutter to open this, talk about slick!! I seen some very tiny flakes that I was able to get out, but couldn't feel them. Here is a picture I took, I tried my best. Red paint pieces are from ages...

    Oh, by the way, here is my build thread on this too, where I also show pictures of doing all the engine work (around page 9 or so is engine stuff). https://www.gmsquarebody.com/threads/76-gmc-crew-long-box-dually-gotta-get-it-on-the-road-again.29806/

    I think I may have bent push rods--and other issues (76 GMC W/455 Olds). Crap.

    Yup, I thought the same...dumb (hence the reason I loaded it with assembly lube). However, I wanted to be sure I did crap right so I followed their instructions exact. Keep in mind this was NOT a fresh built engine either. I am going to assume a very low mileage car it came out of. My dad and I...

    I think I may have bent push rods--and other issues (76 GMC W/455 Olds). Crap.

    Correct: They stated no engine priming because they didn't want the lifters to have any oil in them because it would be too much pressure against the cam right away, they also stated no inner valve springs. They stated they want the lifters to naturally build up pressure against the cam lobes...

    I think I may have bent push rods--and other issues (76 GMC W/455 Olds). Crap.

    @Bextreme04 I did all this work myself, and did not actually measure installed height. In hindsight I should have done a lot more than just degreeing this cam and thinking all else was ok....because it wasn't. Also, as I stated above I followed break in to a tee from Comp....no inner valve...

    I think I may have bent push rods--and other issues (76 GMC W/455 Olds). Crap.

    @TotalyHucked I am hoping for the same too! I will be certainly doing what Matt stated above for sure! @85K304SPD this baby will be a cruiser, nothing more. It may pull the camper a bit to local area's. I love the Thumpr sound, hence the reason I chose that cam. As for where the site mentions...

    I have a higher compression (stock around 9:1 to 10:1) 1969 Olds 455 with C heads. Here below is the cam that I have. https://www.summitracing.com/parts/cca-cl42-600-5/make/oldsmobile Here are the springs that are supposed to be installed with the above camshaft...

    @Matt69olds are you speaking of these guys, it says they are in Wisconsin..?? https://rocketracingperformance.com/ When you stated to paint the pushrods, you mean with sharpie like on the valve stem, correct? Would I mark the pushrod with something simple like using a steel 6" rule (flat...

    I think I may have bent push rods--and other issues (76 GMC W/455 Olds). Crap.

    Not yet, plan to tomorrow, or Thursday. I don't think the cam would be flat (man I hope not!!), as I followed the cam break in procedure from Comp Cams right to a tee...and I see no shavings, or any hint of glitter in the oil, it's still as clean as can be. I could make that meme now too, the...

    Well Gent's, all the work into the 76 GMC dually has been worth it, but now I think I may have another unforeseen problem!! Looking for advice here, I think I am on the right path..... Not too long after firing it up for break in, this 455 just did not have the "potato" sound that it should...

    Hood not sitting flush

    These big hoods can be a pain! My hood was just kinked, and it has the braces on it underneath. Good suggestions here, I am going to keep these in mind when my hood goes back on....well, if I can get the hood straight enough! It blew off my parts truck in a wicked storm last year, hit garage...

    Be safe when trying to pull out a stuck vehicle-

    That just sucks. Gotta be so careful, but sometimes in the moment you just don't think of crap like that. This happened locally here to a guy trying to help a stranger out of a stuck snow bank. He hooked up to the other vehicle (back to back), and the other persons receiver hitch came out...

    Is the 8.1 still a dead end swap?

    Wow, that is one nice Suburban!! I would trade you for my '01 3/4 ton with the 6.0 if you want to send that 8.1 out my way and you could do a 6.0 swap instead :cool: Honestly I would like to own a Suburban like that, some of the hills we encounter with our 6.0 I tell my wife "sure wish I had...

    76 GMC TH400---dipstick boot, or no??

    So the 400 in my truck should have a boot?

    76 GMC TH400---dipstick boot, or no??

    Gents, my 76 GMC has an aftermarket (POS) chrome dipstick tube in it. It has an o-ring at the end of it. It will not fit in the trans properly, because the o-ring groove in the dipstick tube is like it should be on half of it, and very shallow on the other half making the o-ring sit out too...
