    Opinions on best newish Suburban or Tahoe

    3 words. Car Wash Brush Screw that hand washing especially the part you can’t see. I ain’t got the time to use 3 buckets and 2 kinds of sponges. Big ole car wash brush takes care of it. Can even do the roof on the bro dozer and the K20 standing flat footed on the driveway! Occasionally...

    Brake Fluid Flush GMT800

    ^What he said. I’ve become a big fan of the lazy man’s fluid flush on brakes and power steering. And sometimes differentials if no drain plug and no real reason to open up the differential cover. If you run the numbers and don’t mind “wasting” fluid at the expense of ease and time, you’ll find...

    86 C20 - Climate control not changing position - cable or vacuum operated?

    Yup. That goes to one of the vac ports on the hvac box. If you take off the glove box door and remove the glove box most of them are pretty easily accessible. Removing and reinstalling the whole thing under the dash is one of those cuss for 2-3 hours the first time and much easier when repeated.

    Gas spilling when filling up

    @texdave It’s gotta be one to the fuel pump, one return, one vent.

    Gas spilling when filling up

    There should be evidence of staining from the gas leaking each time. Although really hard to pinpoint while filling up. Or see up in there. The sender looks new(er) in that picture though. Is the return hooked up? How many ports on your fuel pump? Not really pertinent to the leak but possible...

    Front spring question

    Fine thread is better than coarse as well but moreso in durability if using the tool repeatedly under a load.

    Wobbly power steering pump pulley

    Worth trying. That old pump might last for years. The steering pump on the 77 looks original. Replaced the original leaky lines a year ago and it’s smooth and leak free.

    Front spring question

    Ya tough call. If the truck is otherwise straight then you could put a little coil spacer in the saggy side and see how it looks. 1/2” ain’t much if it drives good. Should still be fine with a smidge of lift? I like cheap simple solutions.

    Dual Battery

    Sounds like you got it about figured out. Nice!

    Adhesive Rear Cab Molding?

    It’s not scary. And you got a wide margin for messing up and it’s still hidden.

    Coolant Hose Popped Off the Thermostat

    That Altitude shouldn’t affect the coolant enough to matter. But you’re correct it affects boiling point, say straight water at like 10kft alt boils at under 200deg.

    Is this a square body?

    Did you get hit in the head recently? Lol

    Doesn’t matter though. Think about your goals with the truck. At this point, that’s not really part of the equation. It will have a NP208 and either a turbo 400 or 700r4.

    A stock 80s 350 is about as anemic as it gets, except for the 70s motors that had even a few less horsepower. Depends on your definition of ok. I’ve pulled big stuff with stock squarebodys with 350s back in the day. You’re ragging it mercilessly to think about towing 10klbs on anything but dead...

    Great idea, except the “factory drop in”option is a NA 6.2 with anemic power. And turboing the 6.2 or dropping in a 6.5 mechanical TD is a project and a rabbit hole you don’t sound experienced enough to go down and not be frustrated. And if you were successful it would still be a muffin...
