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.




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.







Then it was a matter of getting it into its final resting place.


***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.

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.)

Well, you'll at least have a very pretty truck that doesn't go, opposed to an ugly truck that does run... perhaps we'll end up with clean & running trucks at the same time?

Re: Scott's 1972 Chevy K-20. A place to start.

Nice work Scott and congrats on your first start up and drive time! It looks likw some one has a pretty sweet Mega Cab CR sitting there too! How much of the dodge harness did you end up keeping to get the 47RE to shift correctly? I might be doing some swaps using these transmissions soon.

Thanks Ryan. That CR is my buddy Paul's, he's been helping me with the truck, and in turn, I get to help him with his '69 Bronco.

So, for the Tranny, I didn't keep any of the electrical harness. That's mainly because I'm running the 47RH, not the 47RE. But, I do have a series of challenges to figure out with regard to the lock-up and overdrive which aren't done yet.

In talking about my situation with someone else, he'd pointed me to PCS thinking that they may have something to help. I've looked over their site, and two things come to mind. First is that they're really focused on Chevy/Ford transmissions and that they're not a cheap solution.

I've still got to sort out some of the little issues... my power steering fluid hasn't gotten all the air out yet, and keeps foaming over the fill cap. The transmission fill line is loose and fluid is squirting out of there. And I need to get the fill line done for the fuel tank.

Re: Scott's 1972 Chevy K-20. A place to start.

I don't know why I keep thinking you are using a 47RE. Here's the way to go:

http://www.transmissioncenter.net/SwapInformation.htm

A PCS is overkill for a 47RH. If you use a controller, you're defeating the purpose of using a RH. That or use 2 toggle switches.

Yep, that's currently on my list. There's a couple of things that I need to get in order first, like finishing up the fuel tank fill neck, buttoning up the intake lines, etc.

I've reached the just 'cause it's running doesn't mean you're done point.

Wow.. this isn't good. I don't think that the holiday season was conducive to me getting any time to work on my truck. I don't think I've touched it since November.

Speaking of Mr. Burb, I happened to see his beast go rambling through the intersection in front of me this weekend. Not quite enough time to take a picture, but it was a random sighting of a board member...

Ha, for some reason I was thinking that you were down in Cortez… I'll have to ping you next time I'm in town. Both my grandparents and parents own places up by Lemon Reservoir.

Re: Scott's 1972 Chevy K-20. A place to start.

Well, I did manage to get a little bit of time on the truck this last weekend. Still working on finalizing the fuel tank. In the pictures, the bed is off the truck, but I hope to get it all back together this coming weekend.

When it came to mounting, I had to space this between two of the bed rails, the one right behind the rear wheel wells and the one further back. There's not a lot of room to work with, but I think I've got everything to clear now.

I'm getting ready to install a gas door out of an S10 in the exact same location on my K20, someone just posted and said i cant do the welding until its 70 degrees, if anybody has advice on this i'd appreciate it.

You did a great job cutting the inside of the bed, looking forward to seeing the cover and how you make it!

So, I basically used a 4.5" hole saw on the outside of the bed, ran a 4.125 on the inside of the bed and the floor. The middle line came off of the screws on the side marker and I tried to get the middle between the braces.

The inside bed hole was easy since I used the outside cut to start the pilot hole for the inside. For the bed, I just measured it so it out to be roughly 45 degrees (but also tried to keep it inside the wheel well.)

I'll take some thicker paper to create a template for the cover, and probably just create a lip, rivet it in place, and put the bed liner on it when all's said and done.

I have been shooting for the exact same location, C/L off the holes of the marker and right between the support rails on the floor, but i will take another look as to the location of the inlet on my Boyd's tank before i settle front and aft.

I was however thinking that if i made the upper cut straight across then I could put a lip flange on the top of the cover and have it go under the bed side, then have the sides and bottom flanges of the cover be on the surface. That said i'll see how yours turns out before i get that far, you probably have an idea up your sleeve that will make that rounded cover look way better! then i may steal your idea if ya don't mind.
