1972 SWB Build

[MDPotter]

Are you installing the park safety switch on the transmission? I'm in the middle of reworking my LQ9 harness and trying to figure out whether to keep the switch or not. I have a large grey 12-pin connector in my harness that connects to the transmission-mounted switch. I'm guessing you have a single wire from your PSI harness that connects to the brake switch.

The PSI harness didn't have provisions for the range or neutral switch on the trans. I am using the stock column mounted safety switch. My truck is still wired stock for the ignition switch. So the purple wire goes from the ignition switch, through the neutral safety switch and then to the starter.

I did get a new brake switch that supplies the ecm 12v when the brakes are applied and 12v when the brakes are not applied for the TCC circuit.

Thanks for the info, your truck looks great.

Looks like you used mild steel brake lines? I just put stainless lines on my dad's 66 and it's been a little difficult because the stainless is so hard and it doesn't like to seal without a great deal of tightening.

What engine mounts did you use? Looks like you kept the stock perches but maybe used some kind of adapter plates?

thank you!

I used the stainless steel lines from Inline Tube. If I had to do it again, I would have used the steel lines. I had to make custom lines for my rear axle and I couldn't get the 3/16" stainless to consistently flare. That's good to know it takes some tightening to seal.

I used the stock small block pedestals with energy suspension poly mounts. I just used some cheap adapter plates I bought on amazon. They are 3/8" thick.

Went into the shop and cut down the lower hose and it fits perfect. I had to flip it around to make it work. The direction I thought it would fit was actually backwards.

Hoses look good. Did you go with an overflow tank for your radiator?

Yeah, I am going to. I have a Dorman universal tank kicking around the garage, but I may look in to other options. I haven't really looked in to it much.

Sorry, I haven't updated in a while. We are expecting a baby tomorrow. I've been scrambling trying to get everything in order for that. I have been able to work on the truck hear and there. I decided to back burner the wiring until the end. It was consuming too much time that I needed to be spending on mechanical items. Just about everything is buttoned up on the engine. I broke out the cherry picked to center and align the engine and trans. It is all torqued down now. Once I get it on the lift, I am going to check the driveshaft angles and make adjustments as needed.

I also did some measuring on the brake booster pushrod length. The Tuffstuff booster comes with a short and a long pushrod. Initially, I was going to use the short in conjunction with the Wilwood bullet. But after measuring, I found that the short pushrod/bullet combo was actually .046" too long. The long pushrod measured in at .065" short. After talking to Wilwood, the recommend .062" play so the long pushrod is the way to go. I talk a little about it in the video below.

I am officially at a standstill for a few weeks. I've got to help my oldest with his pinewood derby car. His race is on the 26th so we've got to get cooking on that.

Congrats on the baby! Don't build a pinewood derby truck...they look cool, but go too slow....ask me how I know.

Funny you mention that, my son wants a truck lol

Suggest to him that you make it a "daytona" truck, wedge the front like a door stop, it could look truck-like but it will be faster than a square front. Or, just give him what he wants and let him learn about aerodynamics.

Congratulations on the baby!

Thanks! I think a slant nose truck would be decent. I can add the weight to the "bed" which is ideal anyway. We shall see. I think I may be more excited than he is.

Did you have the baby? Hope all is well

We did! Little baby girl is perfect! We are getting back in to a groove now. I spent about 5 hours out in the shop today. Heading back to work tomorrow.

[1971Stepside]

Congrats! Hope you get some sleep

Thank you! She is actually sleeping quite well. My boys are adjusting well too. So far so good (knock on wood)

I’ve been slowly working on odds and ends on the truck. Going to work on some wiring tomorrow.

Tomorrow is the big day for my oldest. This is the truck he built. I helped him with some of the prep work on the paint and locating the weight. He did the rest. We shall see how it does in the morning.

Boy that brings back good memories. Post up the results and some more pictures if you don't mind...

Thanks. We came in 3rd place. Not too shabby for s blocky truck.

[1971Stepside]

I just feel like it should have been painted red and white! LOL. 3rd isn’t bad at all for a truck.

He originally wanted red and white but changed it to white. I was surprised it do so well. I posited the axles and did the 3 wheel setup. Worked out well.

Amazingly clean truck man! Glad to see the progress, I actually remember seeing you post this thing on KCSR when you got it!

Thanks. It's changed a bit since then.

I'm falling behind in here. I've been working on the truck as much as I can. I am finally making progress. The last year or work is finally starting to pay off.

The motor is all but buttoned up. Fuel tank is mounted. Final wiring has been sorted and started. The big items are the fuel lines, transmission lines, and finishing up the wiring. I am going to tackle the wiring first to get it done. I have a plan and all of the parts in hand or on order. I am going to use relays and parts that I mostly had on hand to get it running. Then down the road, re-do it with the nice Bussmann relay center.

Here are the latest videos on the build. Thanks everyone!

Spent some time this weekend sorting the wiring out on the interior. The LS harness is not integrated with the truck and Dakota module and every which way in between. It took a few hours, but it is almost complete. I ran in to a little bit of a snag with the PSI harness and poor crimps. The trigger wire leading from their fuseblock broke free. After some investigating, half of the crimps inside the fuse/relay assembly are no bueno. I am going to de-pin it and fix them all. I think I am also going to bypass the fuel pump relay in the PSI harness and use my own in the engine bay. The terminals they send with the kit are not large enough for the 10ga wire I am using. I did find the appropriate terminals online, but I think I may use one of my heavy duty relays that I am using for the fans and headlights. Keep the high load relays together. Still not 100% yet thought.

Sometimes, I think my anal retentiveness gets the best of me. I can't leave well enough alone.

Here is a little video of this weekends progress.
