    Broke a 4L80e mounting ear

    Got the tranny out today. Here are better pics of the break. The thing that makes me nervous is how close the break is to the dowel pin hole? Change anyone’s mind about whether or not to get it welded? How difficult a weld is that going to be for a good welder?

    Broke a 4L80e mounting ear

    All joking aside I might have to do that. Having a helluva time finding the stock length pins. These ones came in the mail today, thought they were regular length but they say “extra long”. Racing style for with a motor plate? I’m guessing they’d be too long? There must be something I’m...

    Broke a 4L80e mounting ear

    Gotta come clean here - I'm an idiot. The dowel pins are missing, so they weren't able to help get engine and tranny lined up. pretty sure that's the whole cause of this mess. I didn't realize my screw up till after the first post. And not sure how I missed them. Possibly because I switched...

    2700 ETR based system, was lost, now not so much

    So I have a novel solution to the 4 ohm speaker/8 ohm radio issue that I've used in my '76 vette for years, with no problems. I simply converted the original 2 speaker system to a 4 speaker system but I wired the channel pairs in series, not parallel. So the left channel has a front/rear pair...

    Broke a 4L80e mounting ear

    Thanks for all the help guys. It fits like a puzzle piece although I can’t see the entire crack line. I’m pulling it this week ( trying to decide on either buying or borrowing tranny jack - guy at work has one) and hopefully good ol JB will do just fine.

    383 Vortec/TBI Build Thread

    Well, got the 383 in finally. That was the win for the day, the loss was the broken ear on the tranny, see my earlier post.

    Broke a 4L80e mounting ear

    Cool, thanks. So trans went out for other reasons? Missing bolt/chunk out of bell housing had no effect?

    Broke a 4L80e mounting ear

    Yeah, I haven’t gone out to verify but I think I know why now. Before I even pulled the old motor I pulled t-case because it needs its input seal replaced. I ended up putting the cross member back in to support the back of the tranny without a jack stand. (Front supported by jack stand after...

    Broke a 4L80e mounting ear

    Good news: I dropped in my 383 today and with some effort and monkeying around we got it on the motor mounts with bolts thru them. And then it seemed to be pretty easy to get the tranny to line up. Got the lowest bolts in on both sides, not too much trouble. Then next one up on passenger...

    1st trip to Detroit - 100 years of Chevy Trucks

    I’m in Detroit for a work trip - 1st time ever. Cool city but I especially enjoyed the GM renaissance center as they have a great exhibit of 100 years of Chevy trucks in the lobby. The square was cool (‘75 c10 stepside but really stripped down. Wrong hubcaps?) but my favorites were the ‘56 v-8...

    Starter questions

    It's good. I put in one half 0.02 shim on the outboard bolt and I think that brought it in just right. You guys prolly knew this, but I figured out I can put 12v to the trigger terminal, but nothing to the main motor terminal, and it will pop the bendix out so I can check clearance. A regular...

    Starter questions

    The starter brace came yesterday, pretty pleased original GM, came in sealed “genuine GM” bag and from a Chevy dealership. (Wasn’t sure based on Amazon listing). Fits up nice and can even use original heat shield with just a minor mod of bending or removing a tab.

    383 Vortec/TBI Build Thread

    He just burned new bin on to my existing chip while I was there. PO had him do a tune on it years ago and the chip and holder (ZIF, I think) were replaced then

    Dumb question time....88 Suburban tailgate

    This matches my recollection of when I did my TG conversion. Definitely remember that roller serving as some sort of safety mechanism.

    What is your daily if not square body?

    My DD is a 2012 Cruze Eco, 6 spd manual. (manual availability is a big reason I picked it). Low to mid 30's in town, low 40's on the freeway. My other project: '76 Corvette, owned it for 17 years. Painted 14 years ago or so, rebuilt the original 2-bolt block with vortec heads and a little...

    Starter questions

    @hatzie and everyone else: thanks! Lots of good info. I ordered the front brace. $7 shipped from a Corvette parts supplier (Corvette Central). Still not sure why I can only find them in Corvette catalogs though. Also working on shimming. I think it's going to take a thin half shim on the...

    Starter questions

    1. Did squares ever use a bracket that bolts to the front of the starter on one end and the side of the block on the other? My '76 corvette has one, looks like this, but I don't think squares used them? At least not the later ones? Other GMs? Why did some need it and not others? 2. How...

    Bought the HF one! Still didn't get the motor in today, but I'm finally ready to drop it in.

    Need opinions: DIY TBI Tuning

    Thanks a lot guys. I think I’m going to do a hybrid of my two options. I’m going to buy the moates burner (and a few chips) but I’m also going to work with Dave and see if there’s an option where I could pay him for his assistance and input, e.g. checking my datalog files and then checking my...

    '86 Sub help

    Welcome! My vote is always q-jet in these situations. Cliff Ruggles book is a great start. Doug Roe’s makes a great companion for it. Make sure you buy the rebuild kit from Ruggles as well, or another quality outfit. Many parts store rebuild kits will not stand up to ethanol fuels. I was...

    Dumb question time....88 Suburban tailgate

    I agree about having to climb in to remove the panel to actuate the rods in this case. But as for TG opening regardless of window position (glass missing or not missing) is this true? I can't argue - even my single safety switch is missing such that I can roll my window "up" even when TG in...

    Need opinions: DIY TBI Tuning

    What's everyone's thoughts? Will be dropping in the vortec 383 in the next week or two and will be ready to run it soon. I have a "starter" chip burned for me by Dave W, Old School EFI, while I was watching, that should let me get it running, but it will need additional tweaking to the fuel...
