Re: Scott's 1972 Chevy K-20. A place to start.
So, apparently I've been a little bit lax in my updates. It seems that summer has come and is now on its way out (except that it was still 107 here yesterday.) I've done a couple of little things, but most of the time has been doing other things on the "to-do" list. Spent a weekend cleaning up the yard, front and back. Hosted a surprise 75th birthday party for my father-in-law. Spent a weekend up at my grandparents, always hoping that this visit isn't the last time I see them. Spent a weekend drinking with my brother when he came down to visit. In all, they've been wonderful weekends, just not truck productive weekends.
So, I ended up pushing the truck out of the garage so I could get my work area cleaned up. With parts lying everywhere on the ground, and tools suddenly misplaced, I figured that it was time to clean up the garage. And, while I was at it, I could take a couple of pictures. While I really wish they were, "look what moved under its own power" shots, they're not. Oh well… anyway, I'd call these beauty shots, but we all know what my truck looks like. Oh, look, I do have a garage. https://lh3.googleusercontent.com/-i...o/IMG_0694.JPG My new 'Merican flag flying high. https://lh4.googleusercontent.com/-L...o/IMG_0695.JPG The Dodge D-80 sitting under the bed. It looks like my axle width has increased by 4-6 inches. I didn't do before and after measurements, but it's got a much wider stance in the rear than it had before. https://lh6.googleusercontent.com/-c...o/IMG_0696.JPG Smart aleck kids putting stuff where they shouldn't https://lh5.googleusercontent.com/-B...o/IMG_0697.jpg My son was being a smart arse when he helped me bleed the brakes. We got done, and I came back out to find this new component "installed" on the truck, with the appropriate label. I guess I won't fault him too much. https://lh3.googleusercontent.com/-k...o/IMG_0698.jpg The bump-stop that was added as part of the conversion. https://lh3.googleusercontent.com/-u...o/IMG_0699.JPG Hooked up the air filter. Ended up using a propane bottle (top and bottom cut off) to add as the rigid piece inside the hose & filter so that I had something to clamp down on to. https://lh4.googleusercontent.com/-A...o/IMG_0700.JPG And, a mess of Dodge wiring that is hanging over the side of the truck. https://lh6.googleusercontent.com/-4...o/IMG_0701.JPG Well, at least I got the garage cleaned up, but oddly enough, there aren't any shots of a clean garage. |
Re: Scott's 1972 Chevy K-20. A place to start.
So, I'll preface this with:
In light of the conversation storm that came up after I'd already ordered (and received) the equipment to do my hydrobost and power steering plumbing, I went ahead with the process, instead of sending all of the parts back and ordering all new steel components. Yes, I know it's aluminum. Yes, I understand that there are those of you that are opposed to the direction I took. Yes, I assume all responsibility for the decisions that I've made. That being said, I went ahead and did it anyway. Aside from a little bit of trimming of the left inner fender well, and building a bracket to keep one of the lines off of the steering shaft, I think it looks pretty darn good. And, some day soon, when the engine is running again, I'll be able to test it. But, it is currently in place and everything is tightened down to spec, so we won't continue to argue the point. (Or, rather, I won't, but feel free to voice your opinions.) This was my punch list at the start... https://lh3.googleusercontent.com/-N...o/IMG_0693.jpg Lots of pretty, new parts. https://lh6.googleusercontent.com/-I...o/IMG_0702.jpg https://lh5.googleusercontent.com/-z...o/IMG_0703.JPG https://lh6.googleusercontent.com/-F...o/IMG_0704.JPG https://lh3.googleusercontent.com/-N...o/IMG_0705.JPG https://lh6.googleusercontent.com/--...o/IMG_0706.JPG https://lh6.googleusercontent.com/-c...o/IMG_0707.JPG https://lh3.googleusercontent.com/-T...o/IMG_0708.JPG https://lh6.googleusercontent.com/-8...o/IMG_0710.JPG https://lh4.googleusercontent.com/-u...o/IMG_0711.JPG https://lh5.googleusercontent.com/-F...o/IMG_0712.JPG And this was my punch list at the end. I got to cross 5 items off, and I'm pretty darn happy about that. https://lh5.googleusercontent.com/-u...o/IMG_0713.jpg |
Re: Scott's 1972 Chevy K-20. A place to start.
Well,
I forgot to report that I had some "slop" issues with my original shifter setup. While it was a solid set-up mechanically, I had not taken the rotational forces into account when shifting. There was a little bit of torque that would come into the shifter as slop. Old Setup: https://lh5.googleusercontent.com/-Y...o/IMG_0681.JPG New setup includes a second shaft running in parallel to keep the twist out of the system. https://lh4.googleusercontent.com/-h...o/IMG_0735.jpg And, as you could see in the first picture, after the transmission tunnel was cut up I hadn't had a chance to put the rubberized undercoating on it. So, I took the opportunity to do that since I had it out of the truck. https://lh3.googleusercontent.com/-m...o/IMG_0730.JPG And, everything being put back together in the truck. https://lh4.googleusercontent.com/-i...o/IMG_0733.JPG https://lh4.googleusercontent.com/-J...o/IMG_0734.JPG https://lh4.googleusercontent.com/-h...o/IMG_0735.jpg https://lh6.googleusercontent.com/-L...o/IMG_0737.JPG https://lh5.googleusercontent.com/--...o/IMG_0738.JPG https://lh4.googleusercontent.com/-Z...o/IMG_0740.JPG |
Re: Scott's 1972 Chevy K-20. A place to start.
Since I finished up the PS/HB lines, and gotten the inner fender back in place, I went ahead and put all of the air duct work back in place. The color is what I had available in the house that wasn't balck, white, or primer. It shows a little bit yellow in the photos, but it's really tan.
https://lh5.googleusercontent.com/-r...o/IMG_0731.JPG https://lh4.googleusercontent.com/-H...o/IMG_0732.JPG Then I moved around to the other side, and worked on the radiator lines. Ran the two to the heater box, and bridged the two others that were open for the transmission heat exchanger. It's basically a quick bypass line. https://lh6.googleusercontent.com/-o...o/IMG_0746.JPG This is the bypass for the heat exchanger, tucked behind the alternator. https://lh5.googleusercontent.com/-w...o/IMG_0747.jpg Back to the Vintage Air system. I still need to figure out a cover for this. I've got a couple of ideas, but I really don't want to go back to the giant plastic sheet that came with the system. https://lh6.googleusercontent.com/-t...o/IMG_0748.JPG All tucked under the turbo. https://lh4.googleusercontent.com/-l...o/IMG_0749.JPG |
Re: Scott's 1972 Chevy K-20. A place to start.
And, last but not least for the weekend, I finished up the transmission cooler lines. Since the old radiator is out of a BB/Auto, I went ahead and used that as the cooler. The transmission cooler that originally came with the Dodge is serving as a cooler for the HB/PS. I'm a little worried that it's 5/16" line, but we'll see. I would have liked to go a little bit bigger, but in the grand scheme of things I think it'll be fine.
https://lh4.googleusercontent.com/-S...o/IMG_0741.jpg https://lh6.googleusercontent.com/-T...o/IMG_0743.jpg https://lh4.googleusercontent.com/-l...o/IMG_0744.jpg https://lh5.googleusercontent.com/-h...o/IMG_0745.JPG While I didn't capture the punch list this time, it really leaves me with the electrical and fuel to go. I've still got the lower radiator hose to contend with, need to mock something up for that. The temperature was pleasant this weekend, and not the 110 that I've been working in over the summer. Oh well, it's Monday, so it's back to the grind... |
Re: Scott's 1972 Chevy K-20. A place to start.
I am concerned that with trans shifter mounted on the body and solid linkage to the trans that engine tork, frame twist or cab movement might shift the trans. I had that experience in the past.

Re: Scott's 1972 Chevy K-20. A place to start.
All though I'm not really digging your trans linkage, I think it should be ok. I really think Lokar should have just provided a cable and some other brackets and that would be a sweet set up. Let me save you some time and hassle, GO GET ANOTHER TRANSMISSION COOLER AND INSTALL IT SOMEWHERE. That stock one located in the radiator isn't going to cool for crap and you will have issues. Like fry your trans issues. That yellow burb I did has 2 external coolers on it to keep the fluid below 160 and one cooler has an electric fan on it to be used while towing. Your trans fluid needs to be cooler than your engine coolant temp to operate optimally and the way you have it, it'll always be over 180* at when the engine is warmed up.

Re: Scott's 1972 Chevy K-20. A place to start.
I second the separate tranny cooler. Build a bracket and mount off your frame and wire an e-fan to it, plumb 2 short lines and be done.
Looking at your To-Do list, you might look at my build if you haven't already. I used my factory tank. Just had to drill a couple holes (vent and return). As for wiring, there is not much to it. Hardest part is getting the right field wire combination for hooking up the Chrysler alternator/regulator. I have done 2 now so it is becoming a walk in the park. Feel free to ask for help if needed. |

http://i1321.photobucket.com/albums/...ps2c8b9a16.jpg I was considering doing something similar, and staying with the stock tank, but then I decided I really liked the Dodge's 40-20-40 seat instead of my stock bench. After I put that in place, I realized that I couldn't use the stock fuel tank (evidenced by the second picture in the series below.) https://lh4.googleusercontent.com/-s...o/IMG_0529.jpg https://lh6.googleusercontent.com/-n...o/IMG_0535.jpg https://lh5.googleusercontent.com/-A...o/IMG_0537.JPG So, after a bit of research, I've found someone using a tank from a square-body suburban. http://67-72chevytrucks.com/vboard/s...d.php?t=551269 I've done some cursory measurements, and also checked online. There are three sized tanks that the Suburbans came with: 25 Gallon: 28-3/4" x 28-18" x 10-3/4" 31 Gallon: 28-3/4" x 28-18" x 12-3/4" 40 Gallon: 35" x 28-3/4" x 13-1/8" (Sizes verified on LMC Truck, O'Reilly & Napa Auto websites) I think that the 40 gallon tank will be a bit too long behind the rear axle, but the size of the 25 & 31 should fit between the frame rails nicely. I've been putting this part off since it'll likely require a run to the junk yard to get all of the parts that I want to make this happen. Dragging everything around in a junkyard when it's more than 110 degrees outside didn't sound like fun, so I focused on other things. Now that those are starting to close out, I'm reviewing this option again. Now, for the conversation around the transmission cooler. I don't disagree with any of the conversations or points that you guys have thrown out. I'm reviewing this option, and looking at a different implementation. While I agree with you on some of the points you've made, I'd like to hear more from you guys on this. Ryan mentions that he worked to keep his at about 160. I've scoured the websites of transmission shops and ATF companies and seen that the max you should run is about 175. There's one website out there that discusses the temperature as it relates to longevity and provided a chart discussing the temp and how many miles it'll be good for before it breaks down. (Yes, it's the internet, so I know there's about a 50% chance of truth, which is why I'm actually asking for this discussion.) Degrees F Miles 175 100,000 195 50,000 215 25,000 Basically, a ratio where every 20 degrees = a 50% reduction in the life of the oil. So, if it's running at 185 degrees, then it "should" be good for about 75,000 miles. I know that everyone's rig is a custom built application. Most of what I do in mine is camp and 4-wheel (like Mosesburb). At most, I have a 4x7 utility trailer that I pull behind my truck that I load with the stuff I don't want to have in my sleeping quarters when my camper shell is on. Adding to that, in the 14 years I've owned the vehicle, I've never put more than 3k on it in a year, mostly weekend driving for the home-owner duties, and a couple of hunting/camping trips a year. With a better explanation of what I'm building the truck for, is this still a critical item? (Again, I'm asking for feedback on the topic, this really isn't a "troll" trying to start a religious battle.) |

Scott, on the tranny cooler I say put a nice big one on now. If you are out trying to climb a hill and your trans gets hot, now you're against another hill and you need to climb it and the trans fluid boils and fries a clutch pack. Now you just cost your self a rebuild compared to just buying a decent cooler now. For $50 or so you should be able to get a decent one and will be better than what you have now.

Past 2 i have done: used factory working dodge alternator. about a external regulator for 92 D250 ($16). I believe it is 4 wires. I could take pictures if you are not good at schematics like me. Reason I used dodge Alt is because i already had it and was familiar with wiring it up. Pros for GM 1-wire... ~Obviously 1 wire hookup (clean and simple) VS. Dodge 4 wires and a VR mounted somewhere ~New GM: $54 (Napa - w/o discount) VS. New Dodge $214 (napa - w/o discount) Cons: Need to build brackets and swap pully |
Re: Scott's 1972 Chevy K-20. A place to start.
Well, I didn't get anything done on the truck this weekend, mainly due to the 1500 mile road trip I took from Phoenix to San Jose and back. But, I finally picked up the 1929 Ford. It took us a whole hour to get it running. New battery, replace some shorted wires, a little bit of starter fluid, and away she went. Here's a couple of pictures. Yes, I know this is a Ford car, not a Chevy truck, but we're all car lovers here, so enjoy.

Re: Scott's 1972 Chevy K-20. A place to start.
Now, admittedly, I haven't been posting a lot of information about the truck on the forum lately. It's not to say that I haven't been working on it, just that I haven't had time to due to the overall number of things going on.
To bring you up to speed... I decided to go with the square-body suburban 31 gallon gas tank. That required a little bit of fabrication on the back end of the truck. To start, the rear cross-sill (the one with the light plug) came out, and was rotated 180-degrees, and became the front brace for the fuel tank. https://lh3.googleusercontent.com/-H...o/IMG_0811.jpg https://lh5.googleusercontent.com/-l...o/IMG_0812.jpg This effort was followed for quite some time with lots of measurements. I needed to have the fuel neck clear the frame, but at the same time not be so tall as it would bump into the bottom of the bed. Likewise, I needed to play with it front-to-back as so to sit between the bed rails. Once that was done, I finished the calculations and made the brackets. https://lh3.googleusercontent.com/-D...o/IMG_0816.JPG https://lh3.googleusercontent.com/-Y...o/IMG_0833.JPG https://lh3.googleusercontent.com/-n...o/IMG_0834.JPG Then it was a matter of getting it into its final resting place. https://lh6.googleusercontent.com/-S...o/IMG_0836.JPG ***Note: The rear brake line is a temporary solution, and will be getting adjusted either today or next weekend. I'll re-work the bracket and provide more substantive support across the frame before joining to the soft-line on the axle. https://lh6.googleusercontent.com/-P...o/IMG_0837.JPG |
Re: Scott's 1972 Chevy K-20. A place to start.
After that, we ran the fuel lines, topped off the fluid levels, and:
Then it was around the block: And around the block again... Followed by a quick trip to the gas station (since we'd only put a couple of gallons in the truck to fire it up.) https://lh6.googleusercontent.com/-y...o/IMG_0840.jpg |
Re: Scott's 1972 Chevy K-20. A place to start.
That sounds nice! congrats. i may be a little jealous. can't wait to make bad air with mine.
