My Little Red Muscle Truck
« on: October 22, 2023, 11:04:21 am »
As I said in my intro I’m starting a build thread.  This will be my version of a Muscle Truck.  This may be the last square body I own, so I plan to enjoy it!



It’s an 85 cab and front cap sitting on a 76 chassis.  Salvage title, but that doesn’t matter to me.

I recently finished a completely off-topic project and was looking for something else.  This is the other project:









Since it’s off-topic for this forum, I won’t talk about that again after this unless someone asks.  The car is an Austin-Healey replica that I completely redesigned.  Custom 3-link suspension.  It’s LS powered with a T56.  Just about everything in the pictures except the body I fabricated or modified.  It was an eight-year full custom project.  I’m 65 now and don’t want to spend that much time on another project before I can enjoy it, so the truck won’t have nearly as much custom fab work involved.  At least in the beginning.  I might build a custom rear suspension later on.

The truck is solid, virtually rust free.  When I built it the first time, I had enough experience with these old trucks to know where they were rust prone and applied some coatings to help prevent any from happening.  I might find some during the build, but so far, I haven’t found any.

Chassis was rebuilt, but I’ll go over it just to make sure everything is still good.  The front wheels are pretty much roached by brake dust, so I’ll replace them with something else.  Probably with a bigger diameter tire than the 15’s that are on it now.  15’s are getting harder and harder to find.  I’m looking into 17’s or 18’s, but that’s about as big as I want to go.  I might luck up and find a good used set and save some cash.

I moved the gas tank to the rear and also moved the filler door to the rear quarter.  That was pretty much the only body mods except for a rear roll pan.



The tank was a custom job and was just bare steel, so I imagine its full of rust by now.  I will be replacing it with a Suburban tank from an 87 and going with an in-tank EFI pump.  I’ve already ordered all that stuff.

The engine/trans combo will be a 6.0/4L80E.  I picked up an old LQ4 drop out that a friend has had sitting in the corner of his shop for several years.  Mileage unknown, but everything looks good.  Came out of a wrecked ¾ or 1 ton van.  Cable throttle and non-DOD.  Harness and computer all look good and usuable, just dusty.



I’ve ordered a set of mounts from Tejas Steelworks for this.  I could build them, but there’s no need.  The engineering is already done and I can just get on with the program.

I’ve collected a bunch of car stuff over the last 40 years, and I’m planning on using as much as I can and selling the rest to help fund this build.  I have about 75% of a Ford 9” that I’m going to finish and put in this truck.   It’ll have a 31 spline Tru-Trac (sp?) diff, 3.50 gears and disc brakes.  Using an old Lincoln housing I have had stuck back and a chunk (3rd member) left over from another project.  The disc kit I bought this year while at Cruizin the Coast.  Still need to order the axles, weld on some spring pads and get the whole thing assembled.

This project will be built as a practical hot rod.  Something I can use anytime I want to and actually haul or tow with.  The Healey is a toy, like a motorcycle, a ton of fun to drive and play with, but not very usable for anything practical.  When I was much younger, my buddies and I all had hot rodded trucks.  We hot rodded them because that was what we had.  They were cheap and the old smog engines were pretty puny, even by the standards of the day.  140 HP out of a 350 was really bad.  Hot rodding them made them much better to drive.
 
It won’t be getting show paint, in fact, I plan on painting it myself since I painted it the first time.  I used to be silver.  It’ll still be red because I don’t want to paint the firewall and door jambs.  It’s torch red now, but that might change a little.  My plans right now are to get it running and driving, then work on making the interior a nicer place to be.  A better seat, power windows because my bad back don’t like stretching over to roll the windows any more, sound deadening, sound system, AC/heat and maybe one of the nice aftermarket instrument clusters.  No digital stuff though.

Having been around at the start of the square body production (and then some), I’m amazed that some of the project trucks I see cost more than the trucks did when new.  I remember when a parts truck might cost $50 or be free if you would haul it away.  A decent truck that needed a little work might be $300-$400 and a nice-looking runner could be had for $700-$800.  For that kind of money, all it needed was your butt in the seat!  Guess I’m getting’ old!

So that’s the start.  As always, my plans ARE subject to change without notice, but what I’ve laid out is pretty much the plan.  Let’s see where it goes from here!

Great story, you could be my older brother by a couple of years.

Look forward to your progress!

Ok gang. It’s been over a year since I started this thread. Much has happened in my life in that time and things didn’t go quite as I had planned or hoped. My intentions were to get started on the build in earnest right after Christmas 2023, but my mom got sick right after New Years and spent the next few months in and out of the hospital before passing away in March. On top of that, I injured my hip in January and couldn’t get around very well for about 5 months. With everything that was going on, it was June before anything really got rolling on this project. That’s when things started falling apart on the truck “plan”.


I have a few short updates already done and will be posting them in the next few days. Here’s the first:


Since the engine and transmission were important parts of the build and sitting in the way in the middle of my shop, I decided to get them cleaned up, checked out and ready to install. That’s when I discovered that the engine would not make more than about a half of a turn before stopping dead. It took much fiddling with converter bolts to get the transmission separated from the engine since I couldn’t get to all the bolts and had to take them out one flat at a time with a long open end wrench. What a pain!


After getting the engine on the stand I decided to pull the heads and get a look at the bores. Now I’m not an engine expert by any means, but I don’t think the cylinder should look like this!





Needless to say, this was a gut punch. Not only was it full of rust, but there were pits rusted in the bore deep enough that it would have to go .060 over to safely clean up. Might as well go to 6.2 pistons which would be .065 over. I really didn’t want to go that far over unless I was forced to and I thought there might be a better engine out there somewhere. Sooo, the search started for engine number two.


I had my sights set on a 6.0 or 6.2 and passed on several 5.3’s. A 5.3 would probably have done anything I needed to do, but I’m old school and wanted the bigger engine.


After several weeks of looking and calling, I found an early 2000’s 6.0 in a van at a salvage yard about 30 miles from my house. I had made up my mind that I would not buy anything else unless I could hear it run or it came with a guarantee. I have known the salvage yard owner for many years and he gave me a very good price on the engine and trans combo. It fired right up and seemed to run very well. He was pretty sure that the engine had been replaced at some time in the past and considering how it ran, I had to agree. The transmission went in gear and everything seemed OK there. Good enough! The next week I had it sitting in my shop.

For future reference, pull the transmission away from the motor with the torque converter still attached to the flex plate. It will just hang there.  ;)

Thanks.  I knew I could do that but was trying to keep from making a big mess on my shop floor.  Didn't have a drain pain big enough to catch all the oil in the converter without missing the pan.

With the engine and transmission finally squared away, I moved on the actual truck.  With help from my SIL, we pulled the front cap, extracted the old clapped out 305/700R combo and pulled the bed.  Of course, being the deep south, we had to do battle with several well-entrenched wasp nests along the way.  We also spent some time pressure washing everything.  The old exhaust was cut out, too.  After that, we moved it into my shop and looked it over.














Most of the original chassis build held up pretty good and if I wanted to, I could reuse everything as is.  That is, except for the rear shackle bushings.  They didn’t fare so well.  Actually, they don’t seem to exist anymore!  This would absolutely explain the horrible squeaking the suspension was doing when we moved it to my house.





I’ve had plenty of time to think about and plan this build in the last year.  So, where am I headed?  My original plans have changed a little bit, but, of course, they usually do on all my projects.


I’ve owned several square bodies in my life.  Not because they were cool or the “in” thing.  I drove them because they were what I could afford.  I hot rodded them because they were what I had available, but I never could quite build one like I wanted.  I’ve decided to build the nice truck I always wanted.


I want it nice, but not too nice to enjoy.  A clean daily driver type truck, definitely not a show truck or trailer queen.  It’ll get painted, but I’ll probably do it myself, so it definitely won’t be perfect. It might have a few custom touches here and there, but nothing that will hurt it’s usability.


It has to be as reliable as an anvil.  I don’t have any desire to make my own personal Roadkill episode every time I take the truck out.  My back is about as flexible as a 30 year old gas hose and crawling around in a parking lot making roadside repairs ain’t my idea of a good time and nobody is following me with a camera crew and refreshments.  That’s why I’m keeping things fairly stock and simple in the drivetrain.  The few hot rod things I’ve done to the engine shouldn’t hurt its reliability.  The cam is a low lift version and spring life should be fine.  Most critical parts should be available from any big parts store.  The main exception to this is the Holley Terminator X Max ECU.  I’m running a Holley HP on the Healey and am familiar enough with the software to tune it.


I also want it to handle and drive well.  I’ll keep the 2/4 drop, but will definitely be swapping to tubular control arms to improve the geometry.  It’ll get better shocks.  The truck already has sway bars front and rear and those will stay.  I’ll also be adding a quick ratio steering box, too.  The front sway bar will have to be modified to use with the tubular arms, though.


The interior is where I want to do things really nice.  Completely upgraded trim.  Headliner that it never had.  Upgraded gauges. Bucket seats.  Custom console with a B & M Megashifter.  Nice stereo.  Decent speakers.  Sound deadening to cut the drone.  Rebuild the original AC/Heat.  Modern cruise control.  Probably GM, but could be a Rostra.  Make it comfortable enough to be in for hours at a time and drive anywhere in the country.


That’s about it.  That’s a lot, but not nearly as much as my last project.  I want to do as much as I can in stages and still be able to drive the truck, but I have a lot to do in the first part of the build to make it remotely driveable again.  Let’s see how that works out!

Nice.  8)
For people in my "economic demographic" building a hot rod is a slow process.
I just keep doing little stuff when I can.
Looks good.  8)
