    Wheel lug rings

    Most square duallys had them from the factory, so it’s a factory part. Sent from my iPhone using Tapatalk

    Wheel lug rings

    Does anyone know where to buy the rings that allow you to use acorn lug nuts on a dually with steel rims? I have two and need two more ASAP. I bought a truck without them and I want to use acorn lug nuts on it. Sent from my iPhone using Tapatalk

    8.1 4l80e swap

    I’m looking for a low mileage block, but i know on the ls motors there’s an o ring that goes bad and causes low oil pressure. Is there something like that on these motors? Sent from my iPhone using Tapatalk

    8.1 4l80e swap

    Ok, so this is going to be my questions/ build thread for this project. I have a 1987 k20 that currently has a 350/th400. I am wanting to swap this out for an 8.1 and 4l80e. At this point I have bought nothing for this project but plan to have it done by spring. I am not planning on any mods to...

    Well I think you guys have talked me into an 8.1/4l80 combo. I’ve done some research and this seems to be the best option for me. Sent from my iPhone using Tapatalk

    A set of injectors for a 12v aren’t actually all that bad. If I could find an 8.1 It would be sweet but they are hard to come by Sent from my iPhone using Tapatalk

    Big blocks are fun but around here they are well over 1k for a 454 that needs rebuilt. Sent from my iPhone using Tapatalk

    With tires at $300 a piece I don’t think I could afford that kind of power. Sent from my iPhone using Tapatalk

    Well that’s definitely something I’ll think about. For whatever reason tho the 8.1 is hard to find around me. Sent from my iPhone using Tapatalk

    Engine swap questions

    Time isn’t a constraint. The truck isn’t going anywhere until the salt is long gone anyways and I have a heated shop. The crate is without argument the easiest. I like the reliability of the efi and have heard nothing but good things about it so that’s what makes me wanna go that route. The LS...

    Engine swap questions

    I like the 8.1 but for some reason I can’t leave anything alone so I need room to get more power and at this point there isn’t a lot of aftermarket for the 8.1. And I’m not necessarily looking for cheapest but a combination of cheap, fuel economy (not hugely important), and potential future...

    Yeah yeah I’m sure. Trust me tho if I could afford to do it my option wouldve been the Allison with a 24v. But that’s too expensive so it’s a 12v and not an Allison Sent from my iPhone using Tapatalk
