1955 12 Valve NAPCO Clone

[6BT 56]

Hey Luther . Did you ever figure what electric fan to use ?

[Truck Guy99]

This is a sweet build man! I always wanted to do this to a '55 chevy 6400 (2 ton) I wanted it on a 1 ton 1st or 2nd gen 12 valve cummins dually. Hauler or stake body, original sun baked farm truck paint, a few dings, and some plain 20 inch steel rims. Add a receiver hitch and a gooseneck ball. Again, old looking farm wheels but with modern tires and safety. Put in seat belts, make the interior look like it just rolled off the assembly line in 1955. Black or grey tuck and roll interior. Fuel tank between frame rails under the bed. 4wd manual transmission.

Thanks man! I agree with you. I would like to take a long flat bed or dump truck in this year range or a 60-66 C60 and find a wrecked non intercooled D250 for a drive train swap. That way it would still be a 6 cylinder and you wouldn't have to worry about the intercooler. Plus you would have the low gear of the Getrag combined with the 2 speed rear axle and overdrive for cruising. I admit that I have a problem of projects that I dream up

By the sounds of the truck you descibed you would like this truck Rock Tonka is doing. It is a great build and a beautiful truck... http://67-72chevytrucks.com/vboard/s...d.php?t=409469

Here are some poser pics when I got back from my ride around the neighborhood yesterday. First impressions were pretty good. Alot of little problems arose but the are easy to fix compared to injection pumps and injectors now.

I got my headlight switch in and got my harness all wrapped with the harness wrap. That stuff is great. It is a much cleaner appearance and easier to apply than electrical tape. I hope to get some pictures of the harness tonight to add. I plan on working on wiring most of the night.

[Truck Guy99]

Did you have to modify the hood, inner or outer fenders, grille, bumper, or the headlights? How did you wire the brightness switch, headlights switch, and blinkers?

I only cut the inner fender and the core support to fit the intercooler and the intercooler in it. I didn't touch anything else. All the electrical system is original 55 truck stuff. I just run main harness power wire to the starter to get power to the system. The truck didn't come with blinkers.

Looken good. Man I cant tell you how much i love your mirrors . I have the small crappy ones. Shake a lot and the drivers one all you can see is the spare mounted on the fender. Off topic but after seeing the pics of your chevelle I thought you should see the 69 chevelle in the alternate tinkerings section. He put the orriginal body over top of a cup car Chassie . Way too dam cool!!! Any thought on what your going to do for a air filter?

Thanks! I checked it out! That thing is awesome. Looks like something Smokey Yunick would build. On my air filter I am just going to run the original filter piping and filter and just run some angle iron braces to the inner fender. I really don't want to spend alot of money and time waiting for 90 degree elbows to come in. I know those big honking air filters are expensive too but I hope to get one soon.

[6BT 56]

I have my stock air stuff too. i keep thinking of using it but the duct looks like one of the arms of the robot from lost in space. i keep hearing " danger danger " makes me think I should do somthing else. but what? i'm running out of funds on this old girl too. I had all the $$ from all the napco stuff I took out and the 235. Im not over budget but there;s no extra. lol.
I just may have to use the lost in space setup for now untill i can build sumting more period correct looking . there is a ton of space in the fender behind the headdlight. I may just look ino sumtin back in there .

That chevelle sure is cool. I have a poster of smokey's 66 or 67 like yours in my old shop at my mom's. blk and gold. I love to read abt all the old cheating stufff smokey did in the day . I want to read his book some time .

When you wired the starter, did you make it work on the key or the starter pedal? If the floor starter, how did you make it work? Pics? Thanks in advance

I used the ignition switch because my truck was missing the foot starter when I got it from the junkyard. I would think it wouldn't be too hard to rig up?

Hi Luther . Hows it been going ? Anything to report ?

[Luther Grimace]

Not much to report. I got the gauge cluster reinstalled in the truck and got my brake light switch mounted and wired up. I also got the mechanical oil pressure and temperature gauge hooked up too.

I didn't work on it any Saturday but late tonight I pulled it in and removed some leafs from the front pack. Ever since I shifted the engine back it raised the front end up. And the ride got stiff. I de arched a set of these 52s together a couple of years ago when I first got the truck. I removed 2 from the bottom on each side. It lowered it 1.75 inches on each side. It looks much better. I will post pictures tomorrow sometime. I started on cutting up the rear dodge harness to work with the chevy one. Does your truck have backup lights or turn signals?

I agree about the lost in space arm. That is funny! It looks just like it. I am just gonna run it because its free and I have it. All the turbo elbows I have bought take about a week to get here and I hope to drive it to a car show Friday night. I am still waiting on a part from dieselwrencher so hopefully it will show up tomorrow.

I have the same poster! Smokey was a hard core dude!

Here are some pictures of the truck after I removed the bottom 2 leaves. It looks so much better. The tire is centered perfectly in the wheel well for fitting these big 36s. The spring also has a flatter arch which is always better as far as ride is concerned I knocked it out in about an hour last night. You can see the puddles underneath the truck which is from the turbo leaking oil because of my wrong drain back pipe and the other is coming out of the injection pump. It is leaking out of the fuel pin housing. I will have to take it back off and buy another aluminum washer for it.





It lowered the truck about 1.75". Pretty awesome for one nights work. Ignore my shaky writing.

Sorry to be nosy, but how much money are you in it so far and what did you pay for the 55? What did you do with the old parts left from both trucks?

I don't really want to say in case I sell this truck. I can say that it is a very good number that I am comfortable with. If I were to do it over again I could save myself some money by knowing what won't work like highsteer. I could have saved half of what my steering cost based on that. If I could give someone that was thinking about doing this advice it would be to start with a good donor truck. My truck was beat to pieces but it was the only diesel W250 I knew of at a reasonably low price. Most of the money I have spent has been on the engine. The transmission didn't cost much to fix but I enjoy doing this stuff myself as you can see by my pump rebuild. Cummins engines are VERY expensive to rebuild especailly comparing the cost of an old 350 small block. A 6BT rebuild kit without pistons costs 1000-1200 and pistons alone are close to that. I could have saved money by running the old knocking engine but now I have the confidence when someone asks me if it is a good truck I can say yes. I saved where I could and spent where it was most important to me which was steering safety. That stems from a bad experience I had with the Dodge pulling a trailer loaded with a 65 pickup truck and finding out the steering box bracket was broken thanks to the push/pull steering over 50 miles from home on mountain roads. I can say that the body swap itself cost little to no money because I reused all main components from the Dodge and sold what wasn't needed. I scrapped the cab and made some money where I could. The market for early Dodge parts are low. I still have the Chevy frame and I sold the seats. I'll get off my soap box now. Hope this helps!

If anyone is looking for good 5.9 rebuild kits at a good price, here's one place to start..............

http://www.enterpriseengine.com/shop...e-rebuild-kit/

[Luther Grimace]

That is a really good price for all that. What brand are all those parts?
Posted via Mobile Device

[Dieselwrencher]

When I've gotten kits from them it was usually all cummins stuff. I've heard some of it now is Interstate McBee. But their parts are really nice too.

[Truck Guy99]

I kinda figured I'd get an answer like that. I was just asking because I wanted to do the same thing to a 55 as you saw in my dream post. I was just wanting a loose price range without the steering parts. Nice ride though man! How much of a price tag for it? Got a title?

If your truck that you have is in good shape just find a good donor. The body swap should cost little to nothing. Just get a good donor. I saw a non Intercooled D250 that my buddy had sell for $1000 because it had bad ball joints. The real investment is time. I will just have to let someone tug my ear good one day on price. I'm getting the tag swapped over sometime this week. We don't require titles in Alabama pre 74.

[Luther Grimace]

I was going to load my truck on the trailer last night and carry it to the DMV for vin verification since I am still working on wiring. Didn't get far.



I'd love to have a good car hauler one day. What do some of you guys have? To me a goosneck car hauler with a large quality winch would be great. I 'm tired of come-alonging stuff onto a trailer.

[XJAbuzer]

Cut off the rails and make some drive over fenders.

[Truck Guy99]

If your looking for a good car hauler, PJ trailers and trailmaster trailers are both very well built. I have used both and both have held up under LOTS of weight. You could buy some factory sized wheels and tires from the junk yard for "Travel Wheels". Other than that, the only thing I can think of is buzzing those rails off. What about the flat bed in the first pics?

I have a low deck triple axle gooseneck that is 22' deck. Trucks with super wide tires are a pain to get on it due to having to drive through the fenders. But I just put stock wheels on those when this happens. It also has a 8500lb winch on it. Sure comes in handy.
