I miss my Sierra classic crew cab. Is it worth it to take an old truck with close to 300k miles and put a new vortec 5.3 engine in it, new transmission etc, to make it like new?

Depends on your skill level. Early in our business career in the early 80s during the winter rain out. We refreshed two mid 70s Ford Crew Cabs. Luckily we each had different skill sets to make the refresh easier. We did it in my yard, we didn’t have our shop yet. We took everything off but the cabs. Pulling the engines and transmissions. We had Chilton manuals to aid us. We sent the engines and transmissions to researched rebuilders built to our specks. New front end parts, rustproofing, brakes and lines. Fuel tanks and lines. We painted parts and pieces instead of together to lessen mistakes. Not only did we work those trucks pulling equipment. They carried born free campers across country. We drove those two fords and two 83 little Toyota trucks for ten additional years before replacing with diesels one by one. Honestly the Toyota’s never needed anything. Not an easy ride either going up and down pipelines. The best part they weren’t stock. And a blast to drive.

If it's worth it to you, yes. At 300 K, not me.

🤔

 

Depends on the condition of the carcass to me. Does the project truck have good bones? Is it new enough that parts sourcing won't be an issue? Do you enjoy such projects? 

 

You can replace the entire driveline and most or all of the suspension with NEW for a FRACTION of the cost of a new truck and in the end you have a new truck. That is IF the rest of the truck, body, chassis and interior are is really good shape.

    • Maybe.   Maybe.   I don't want to be the one that needs help and can't get it when I need it. That is a legitimate complaint, and how they respond to those legitimate complaints is a big red flag to me.   I don't care how good the product is their conduct is subpar. Some people are fine supporting that for the sake of getting the product they want. I'm not.   To be fair, I haven't seen or touched their product in person to determine for myself the quality of it. I'm not offering any opinion on that either.
    • So if you do nothing and they act on their threats like death to America or Israel. And possibly a nuclear war. Whoever survives wonders why didn’t they listen? Or we do something like every President has said they can’t get a nuclear weapon. We’re at the 10 yard line and it happens the time is now or never. I think I’m ok with paying a little more for gas for awhile. It’s a shame that we now live in a world that’s so polarized. 
    • 4-5-6 fails due to design.  Not enough clutches and not enough piston to clutch surface area.  Also the backing plate can bow.     I'd say converter is two part.  The design of converter chosen, and factory tuning of it aka slipping it in D (also L6) for AFM purposes, as well as locking it up in 2nd gear, sometimes 1st, also it will partially lock up at light loads.  All because CAFE/fuel economy requirements.  A billet converter on the stock tune might hold up better, but would still be subject to the stock tuning and how its designed to lock or partially lock.     The most baffling part to me, is the 2007-2013 6L80s didn't have the failure rate the 2014-2018 ones do.  I've been where I work for almost 17 years now, and I recall maybe 3 or 4 of the 07-13 transmissions getting pulled for something.  14-18 on the other hand, it was at a minimum one a month being opened up.    If I had to guess, I'd say the tuning for the gen 5 engines/6L80 setup and its fuel economy goals had a good bit to do with it.  Also, it was bankruptcy time during these years, so I'm thinking some cost cutting was done for the launch of the K2XX trucks.  See also now the 10 speed valve body issues (more cost cutting).  They blow out some mesh screen in the spacer plate, undersized check ball, and the feed limit valve was aluminum and wears out prematurely.         I don't think it was the HP jump from the gen 4 to gen 5?  The 6.2 in the 07-13 trucks was good for 380-400hp during its life/states of tune, and the 5.3 did 310-320hp.   
    • All this might be worth it had we actually recovered enriched uranium, a WMD, or an actual nuclear deal with oversight. This is a flub of epic proportion, and they all know it.   $5.10 at a station reporting $4.99 last week. Here we go....
