Re: 1972 SWB Build
So what he does is blast or clean the part throughly. He then dusts the part with vht cast coat flat aluminum paint and literally wipes it off with a rag. This seals the pores on the cast and keeps the cast color. It was pretty trick. He does it to all of his cast parts. Turned out really well on the trans and alternator bracket. .
Haha. One of each was hard enough on my wallet. I placed the order this afternoon. That’s the last of the big parts. A lot of nickel and dime parts left. |

Re: 1972 SWB Build
I saw Boyd’s was having a sale with free shipping. I went ahead and ordered my tank. What radiator did you go with? Fans?

Re: 1972 SWB Build
I got in on the sale as well. I went with an Entropy with fans. I bought it all from Travis at Pro Performance. They make it so easy. It was a package deal.

Re: 1972 SWB Build
The motor is in. We had a blizzard forcasted to come in on Sunday so we hoofed it and got the motor in on Saturday. Everything went smooth. The only problem was my mistake, I put the motor mounts in the wrong place on the adapter plates. Easy fix.

Re: 1972 SWB Build
A few black Friday goodies showed up today. I spent some time working on the truck this weekend. Stripped down the engine bay harness to rework it a little to work better with the LS harness and generally clean things up. I installed an AAW complete harness a few years back. I also took the seat out, removed the tank, removed the gauges and starting thinking about how I am going to run the LS harness. I believe I am going to mount the ECM, TAC, fuse panel under the seat, and Dakota modules under the seat . I want to keep the clutter under the dash to a minimum.
I also bought a filler neck and cap from Boyds to plug the hole in the side of the cab. I think it turned out perfect. I am going to weld a flat plate to the backside to seal the neck from water as well as use it as a keeper to keep the neck from being pulled out. Waiting on the Entropy rad to come in. Hopefully by Christmas. I am planning on hitting it hard again Wednesday night to knock out some of the piddly stuff. |

Re: 1972 SWB Build
Keep me posted on the LS harness. I'm trying to decide where to run mine as well. Under seat or on the radiator support.

Re: 1972 SWB Build
I'm really leaning towards under the seat if I can make the harness work for me. This PSI harness has a decent amount of wire from the motor back, so I think I can make it. I am going to pop the hump out and lay the wires in this week to confirm. I'd like to have all of the computers under the seat and out of the way.

Re: 1972 SWB Build
After doing this myself, I'll give you a little heads up. The ECM should fit fine, provided your PSI harness is long enough. However, the Dakota Digital box isn't likely to work under there. The display cable they give you is too short. I believe you are required to run a specific type of cable, but I don't remember what that is (CAT5?). I want to say it has a maximum length per DD, but I could be wrong. You'll need to look into that a bit before you get too far along, or you may end up redoing some work. Good luck, I hope it works out for you.
Nice parts too!

Re: 1972 SWB Build
Well, I wanted to put it on a plate I fabbed behind the seat on the passenger side, but my harness wasn't long enough. It sits on the floor under the passenger side of the seat. The wires come through the back side of the high hump, just before the seat.

Re: 1972 SWB Build
This is exactly where I was hoping to bring my wires in. I am going to pull the carpet tonight to see if I have enough room for a 2" hole in the backside of the hump for this grommet.

Re: 1972 SWB Build
You should have room. I'm pretty sure that's the size hole I used, but maybe 2-1/4"?

Re: 1972 SWB Build
To be honest, they both seem like great radiators. The lifetime warranty and amazing customer service at Pro Performance tipped the scale for me. I'm going to get some new radiator rubber mounts at lunch from the dreaded LMC so I can get it mounted this weekend.

Re: 1972 SWB Build
I couldn't wait and had to slip the radiator in. Man it looks good in there. One thing of note, and I am sure I'm not the first to notice this, the top inlet of the radiator is lower than the fitting on the top of the water pump. I assume this doesn't matter. My thought are the hump in the hose is now going to be the highest point in the system. It may make purging the air a little tough. We shall see.
FYI, anyone local looking to buy odds and ends from LMC, they gave me a 30% off coupon when I was paying today. I spent a whopping $6 on new rubber isolator bushing for the lower radiator. |

Re: 1972 SWB Build
I'll be in KC in March for a concert. I plan on going by LMC at that time to pick up some items. Radiator looks great. My research shows you need a Gates 21439 upper hose and a Gates 20687 lower hose. Let me know on the ones you use. I'm glad you are figuring all this out ahead of me LOL

Re: 1972 SWB Build
Started working on the wiring harness layout. It looks like the PSI harness is the perfect length to mount the ECU under the seat. My plan is to mount the ECM and fuse/relay panel on the passenger side. The Dakota BIM and gauge modules on the drivers side. I'd like to mount the TAC module under the seat as well. but I would have to lengthen the the harness between the TAC and pedal about a foot. The harness from the ECM is long enough to reach under the dash, so I could mount it under there. I'll just see what is the best route to take.
Fun fact, when you select NO to "OIL PRESSURE WIRING (98-02 F-BODY GAUGES ONLY)" when ordering a PSI harness, they remove the oil pressure wiring completely from the harness. Luckily, the Dakota gauges come with a sender and harness to display oil pressure. Had I known this, I would have said yes to make the wiring a little easier. |

Re: 1972 SWB Build
Nice looking truck, hope to see it around next summer. As for the oil pressure wiring, almost no aftermarket wiring harness companies include that wire since its not needed for the engine to run, and it would only be a single tan wire that wouldn't have the correct end for your aftermarket gauges anyway. Also, don't be afraid to lengthen the TAC to pedal wires, it wont be an issue as long as your connections are good.

I’m still not sure about the TAC module. It will fit under the dash no problem. I can make a plate to mount it and the Dakota modules behind the gauges. I’m still not sure what to do. Going to work on it some more today to figure it out. |

Re: 1972 SWB Build
How is the harness coming along? Ordered mine this morning...any lessons learned?

Re: 1972 SWB Build
It's been slow going. Getting ready for #3 to arrive, so I haven't been able to spend a whole lot of time on it. So far, everything with the PSI harness has been great. My only gripes are nit picky type things. The corrugated loom is a pain in the rump to manipulate sometimes. Not enough to justify spending the extra $125 they want for the braided loom, but enough to make me cuss a little.
I spent a few hours this weekend and tapped in to power and signal wires for everything on the ECM and Dakota module. I also lengthened my TAC harness 2 feet to allow placement under the seat. I'm going work on it this afternoon and try to wrap up the wiring so I can move on to the fuel system and buttoning up loose ends. |

Re: 1972 SWB Build
Wire care makes a split wrap F6, using it on my harness to get rid of the corragated wrap from FAST

Re: 1972 SWB Build
I've been using a product made by Techflex called "Flexo F6" for years. It's very similar to what Jim uses, and I get it off Amazon. Pretty cheap compared to the name brand stuff and works really well. They also have other model products that come in different colors, or true sleeves if you don't want a split loom. Can't hurt to have a few options to choose from if you want the braided wrap stuff.
