    1983 454 vs 5.3 LS for towing

    This is great, expensive, but not at much as a rebuild or swap lol. Seems well worth it, might see if I can fit one on the Yukon as well.

    1983 454 vs 5.3 LS for towing

    Yeah I do have a cooler on it, came with the truck. Looks like a standard mini radiator version. I also have an 08 yukon with the 4L60e, so basically a newer 700r4. It has a factory trans temp gauge so I think ill use that for a baseline.

    1983 454 vs 5.3 LS for towing

    1983 454 vs 5.3 LS for towing

    It has the "Performer 2.0" Intake and an AVS2 carb, but thats it afaik. I had considered a cam and headers as well. As far as the cooling, fan seems to be in good shape, and no leaks from the rad. I may end up with a big 4 core aluminum and some e-fans, might cool better and save a little...

    1983 454 vs 5.3 LS for towing

    About a year ago I bought a 1983 C35 3+3 dually. Its currently a 454 with a 700r4. Fires right up and cruises fine on the highway, I drive it to work regularly. Here's my issue: I want to be able to use it to tow a 5-6000 lb trailer about an hour or so on occasion to get my tractor to and...

    Ethanol Free Or Premium Or Either

    When I got the truck from the previous owner, he put E10 (10% ethanol) gas in it because it was cheaper. When I took the carb apart (was hard to tune, like a dirty carb), I noticed some gel-like substance in the fuel bowls, likely from the older fuel hoses that aren't ethanol resistant like new...

    What have you done to your square lately??

    Amazon actually, 1194 amber and red LEDs. I bought all new lenses as well, rockauto had a couple on clearance for like $6. Probably not restoration quality, but perfect for my uses.

    Only had it for a coupe months, so mostly maintenance items (and my least favorite, wiring gremlins). Full LED upgrade is nice though
