Thanks! There are always room for improvement when they're in surgery center ?‍? Of all things, I really didn’t expect the EVAP to become a topic of conversation ? I don’t feel the canister itself is as important as how the purge solenoid and vent valve operate. From what I remember, the TBI...

If you're still running a 6.2L diesel there isn't much you can do. If I recall correctly, the old non-computer controlled diesels just vented to the atmosphere. The EVAP I added operates exactly as it would on a 1996+ GM production vehicle where the ECM controls the engine mounted EVAP purge...

So next up was to acquire a frame, but not for the reasons everyone is suspecting. I work for a truck manufacturer and actually used our Navistar Medium and Heavy Duty Truck Frame Repair Procedure manual to a tee where the crack itself was ground out and filled with weld then another frame...

So, the big break happened in Mid-June of 2020 but I didn’t get around to tearing into the repair until January of 2021. @zoomad75 and I already had plans to do the 8.1L swap into his K5 and I really wanted to knock that out before tearing into the frame of the K10 knowing it would be a long...

As we got closer to the turn off to the Doll House my cell came alive so I knew I had blip of cell service. Luckily, my other buddy, Bill, left us a few days prior as he wasn’t feeling well so I was able to send out a text with instructions for him to go to my house grab the Power Wagon and car...

Yeah, I guess it has been a long while hasn’t it? LOL Well, ole girl got new shoes a couple months ago and it goes to the local Cars and Coffee event every Saturday morning. That will have to do until Desert Trip season gets here. Figured I’d give a set of Geolanders a shot this go around...

Looks good dude! That RAM mount looks brutal. That one sure shouldn’t shake like a watermelon on a pogo stick like mine did until I added an extra brace.

I sure don't as I don't mess with much AN stuff. AN fittings are like Legos, there are thousands of different ones. You'll probably need to call someone at Earl's or something

Outside of replacing the EOC lines with AN fittings and hose the other option is two pipe plugs in the engine block, remove the drainback valve above the oil filter and send the old lines with the trashman. Neither my K10 or Suburban 8.1 have EOC's, mainly because I don't have room to add one...

If they were in GMT400 3500-HD trucks, then they were 8.1Ls (8.1s were in GMT400s in 2001 and 2002). L21's were only in the big TopKick, Kodiak and P-chassis.

Not really. I’ve seen them around and they are often confused with 8.1Ls because they have coil near plug ignition. They also have a pretty desirable 24x reluctor wheel behind the timing chain crank sprocket that allows the engine to run on an 0411 P59 ECM just like an 8.1L or early LS engine...

That sounds like a decent deal! Depending what you plan to do with it, the Allison may not be a good fit. The Allison eats a lot of power and robs fuel economy out of 8.1s. You’ll get much more power and fuel economy out of them when backed by a manual

No doubt about it. I’ve been preaching for years that manual transmissions exaggerate the bad habits of Detroit lockers whereas the torque converter soaks up the difference on an automatic.

Exactly! I was happy to see it uses a very common fluid as well. As much as I dig NV4500s they are very finicky and quite honestly, I don't think they are all that durable compared to say an old SM465 or even a ZF manual. The only thing a NV4500 really has going for it is OD and it shifts...

You will need a different brake pedal for hydroboost as the connection hole is in a different spot. Those pedals aren’t super hard to come by as there are may CUCV parts sellers out there or comb the junkyards for a squarebody with hydroboost. But, there will be a few bigger challenges as 1981...

Nope, nobody offers a manual transmission in full-size trucks anymore in the US (RAM was the last in 2019) but a new crate Tremec TR-4050 can be had from these guys…. Or try to smuggle on up from Mexico out of a late model GM 4x4. They are much like a NV4500 and come in 2wd and 4wd flavors...

Just another square body with hydroboost. Most 1 tons, big blocks and diesels had hydroboost. Nah, I wouldn’t go backwards on the Tcase to a 241. Not that 241’s are bad, they just aren’t as the anvil a 205 is. I have a 241 behind a NV4500 in my Burb and it works great with a respectable low...

Maybe today. I need to take the part numbers from the Amazon links you sent me and find a different vendor. I don’t want to order these from Amazon because there are some things I don't want the CFO of the house see what they cost ?

A few other updates that are new around here is the K10 and Polar Bear Burb have gained a stable mate. I’ve finally begun building a 1985 K5 Blazer for myself. I’ve always wanted another Blazer since I sold my ’72 K5 over 25 years ago! This K5 will literally be like building a 1:1 scale 1:25...

That's why I was in a hurry.....needed gas! Just kidding, that was actually half tank as the right tank was still full and I hadn't started transferring fuel yet. Does make for an appropriate picture though. Lol
