1964 GMC 3/4 ton build :D
 

Hi guys thought I would get started on a build thread finally lol. I have a web page I have been building for years on this truck but thought to share what I got with this truck on here as well. I am working on getting an l92 and 6l80e engine and trans home here this next week and will getting some photos of it up here and on my webpage here very soon. Definitely doing the speartech harness setup since he can set up a pontiac gto shifter to control the trans od switch and 6l80 transmission without any problems :D.

you can kinda see where I started over 12 years ago on this ole beasty first vehicle I ever bought an downed outright without assitance from my parents. Many an afternoon rolling her down parking garage ramps at work to get her started when the engine oil would kill the starters lol. She has come along way so far and with any luck end of 2011 will be dragging rice burners down I75 with my 4.56 geared rear end.
in these you can see where I am working on adapting the 2008 dodge 3500 disk brake plates to the axle will have more pictures up in the next few weeks when I get hold of the machinist again and we get the delrin plastic pieces for mock up ready. once those are in place will be getting the exact depth and thickness set to make adapters out of 7071 aluminum which he says will be more than plenty for keeping the brakes in place :D

more yet have tons of photos on this truck to play with :D.

Re: 1964 GMC 3/4 ton build :D
 

here are some pictures of the painless 67-72 harness I am heavily modifying to fit in the gmc so I have a lot more circuits to work with.. After about 40 hours work it is turning out beautifully.

Hey Guys,
Got the engine and trans home today now to start cleaning things up on it and getting rid of emissions junk other than what is needed to run this ole boy :D. 1K no tax lucky he has too old a tahoe to put this engine in lol.

Sean

Re: 1964 GMC 3/4 ton build :D
 

got some new pictures of the progress I am making getting the engine to slide into the engine bay. I was working on stripping off cut plug connectors and other misc stuff today, dropped the ac compressor and bracket off the engine along with motor mounts and some other misc stuff. here are some pics. the first tow are of the exhaust flange and my efforts to save it since gm wants 500+ for a new cat y pipe assembly for this engine. this works out great for me since I am doing dual exhaust anyways. also got some pictures of the early classic engine brackets I had stashed away and found yesterday :D

Sean

Re: 1964 GMC 3/4 ton build :D
 

That trans you have is for a 4x4 application. What are your plans there?

Re: 1964 GMC 3/4 ton build :D
 

Hey Captain,
gonna convert it to 2wd model. at the prices they are asking in the junkyards here for them trannies will be cheaper to have a trans shop swap it over to 2wd output shaft.

Sean

Re: 1964 GMC 3/4 ton build :D
 

Yeah, I understand that. It's difficult to even find a late model 2wd trans around here at any price. Are you going to convert to a mechanical speedo at the same time?

Re: 1964 GMC 3/4 ton build :D
 

Hey Captain,
No I have an electronic speedo to use with it. Speartech is going to set me up the harness for the whole thing and he can program the speedo output to work with the speedometer I have. No one as of yet makes a mechanical speedo output for the 6l's yet. Hopefully the future will bring more goodies for it. :D. plus the speedometer sender is inside the transmission on these 6l's series trans since the computer is inside the casing.

Sean

Re: 1964 GMC 3/4 ton build :D
 

I got some work done on the disc brakes for the rear the machinist came over today and we atrted the trial fit of the adapter plate that will mesh the two pieces together. Also got the rotor centering rings as well and they worked perfectly rotor is 100% centered on the rear hub :D.
On the 6l80e going to upgrade the output shaft when it is torn down for the shaft conversion so i wont have any problems with shattering drums in the trans which apparently the 6l80's have a problem with.
Sean

Re: 1964 GMC 3/4 ton build :D
 

Got my 2wd tail housing on order for the trans and have a trans shop lined up to replace the output shaft here in a few months, Dirty dingo slider mounts are on order and will have some pics of the onstall coming up soon when they are on the engine and ready to drop it in :D.


Sean

Re: 1964 GMC 3/4 ton build :D
 

I'm really digging the build. Looks like you've got some awesome plans for the truck. Also, it's cool to see another guy from plano. :metal: Maybe we'll have to meet up and show off our trucks sometime

Re: 1964 GMC 3/4 ton build :D
 

Looking good.. Whats the specs on the motor and trans?

Re: 1964 GMC 3/4 ton build :D
 

Hey Jeremy,
Yeah that sounds good to me. I alooking at next summer being able to putter down the street in this truck :D. You dont happen to be a member of pickups n panels are you?

Sean

Re: 1964 GMC 3/4 ton build :D
 

Sounds awesome, mine's almost road ready again. I used to drive it everyday before I started tearing into it.;) I've looked into PnP quite a bit, I just haven't followed through in actually becoming a member yet. I do plan on it eventually.

Re: 1964 GMC 3/4 ton build :D
 

Hey Jeremy there breakfast meeting is next weekend on the 12th if you want to tag along? I will be taking my sons firebird to the meeting that day. That way you can see if you would like to join the gang they got some sweet trucks especially patricks!!! DROOOLLLLL!!!!!!!!!!!!!! classic trucks magazine once and custom classic trucks spreads on his truck.

Sean

Re: 1964 GMC 3/4 ton build :D
 

what other plans do you have for your truck? Discs etc?

Sean

Re: 1964 GMC 3/4 ton build :D
 

61 it is a factory stock motor and tranny from the escalade 403 hp 445 ft/lb vvt v8 with the 6l80e 6 speed auto. gonna have to watch out for cops when driving 4.03 1st gear in trans plus 4.56 in rear end possi'd shouldn't need much more than factory hp with my truck and the gearing it has.

Sean

Re: 1964 GMC 3/4 ton build :D
 

Sean, I saw your other thread on the T-56 transmission. Are you not planning on using that anymore, or were you ever? Thanks for the info and invite, I'll see if I can make it.

Re: 1964 GMC 3/4 ton build :D
 

Hey Jeremy,
yeah I gave up on that since the trans wasnt gonna be able to handle my truck. Would've blown it up lickity split. My truck is too low geared and too heavy for that transmission. I dropped the 6.0 awhile back thinking might do a cummins swap and found out that was too dammed difficult so am back to gm engineering agin :D. Luckily that chevy finally made a decent engine that really doesnt need hop ups. Sticking with this one since it has the tunability I like and plan on experimenting with after reading the hp tuners and efi live. that and 403 horse plenty enough said.

Sean

Re: 1964 GMC 3/4 ton build :D
 

Well got a bunch of clearancing work done yesterday ont he rear brakes and from what I am seeing going to have to make some some small stainless spacer bushings for the rotor to lug mounts right now the rotor can shift back and forth on the hub and I dont want that happening during braking power application so will see what the machinist can come up with there this wednesday.

Waiting on the dirty dingo mounts and trans tail housing to come in as well so will have some more pics up next week on my days off.

Sean

Re: 1964 GMC 3/4 ton build :D
 

Hey Guys,
Got the dingo mounts in today and looking at these beauties. You can slide the engine back or forwards up to 2 inches. Here are some pics of the mounts off the engine will be painting them tommorrow after I get my errand running done along with some more work to the rear brakes. I am having to wait to have the aluminum adapter blocks shipped in apparently the dallas locations has some wuality control issues with there 6061 aluminum per the company rep today.

These are going to be some sweet mounts since they adapt to the old style mounts. Thinking might be better to powder coat them rather thatn painting since I have a powdercoat shop close by :D..

Sean

Re: 1964 GMC 3/4 ton build :D
 

Hey Guys,
Got the engine brackets painted. Got some news from painless they are working on a l92 vvt with 6l80/6l90 harness setup. They asked me to test fit and run it but since my engine isnt even in or near running I am going to have to pass on it. They are looking for someone to test fit and do a trial run on a vvt 6l80 combo atm. Will have the engine brackets placed on the engine a little later today and go from there my wifes plans for an alaskan druise have put funds on hold until may so will concentrate on other little things while I wait such as my harness installation in the cab of the truck :D.

Sean

Re: 1964 GMC 3/4 ton build :D
 

Got some more done on my modified 1967-1972 painless harness a few more wires to add soon as I get my fuel injection harness in and speedometer wiring and will be finished and ready to install.


Sean

Re: 1964 GMC 3/4 ton build :D
 

Those are some interesting looking motor mount adapter plates. I haven't seen those before.

Re: 1964 GMC 3/4 ton build :D
 

Hey Captain,

Go to Dirtydingo.com he is the guy making those mounts. they run about 150 per set. I stumbled across him a couple of months ago when I started this project.

Sean

Re: 1964 GMC 3/4 ton build :D
 

Next month wont be getting much done other than the brakes. But April I have 3 paychecks lol first and last to the wifes determination to go on an alaskan cruise this summer. Middle check get the machinist paid up on and start gathering the transmission parts together to get the engine and trans in place in the truck.

Sean

Re: 1964 GMC 3/4 ton build :D
 

Cool build! Like to see more pics.

Re: 1964 GMC 3/4 ton build :D
 

here is what I finished working on today took me a little while to get it together but it is done just need to paint the metal bezel now :D.

Sean

Re: 1964 GMC 3/4 ton build :D
 

here are a few more pics of getting the engine compartment ready. The booster is from a 1979 gmc 3/4 ton bought it at oreillys auto. The power steering lines were made by a shop one end has sae american threads and the other end of the power line has a metric fitting for the newer steering pump. The circled holes on the firewall I am going to be working on filling in. Just gonna go simple on it wire brush clean the areas around the holds and jb weld some metal over them. The shifter boot is for the lokar shifter I am using. the 6l80e is like the 700 r4 shifter positioning has 5 positions. 5th being the manual mode which I will do a rocker switch for since speartech knows how to wire it up. Also being doing a tow haul switch as well some where in the wiring works. The center hump you are looking at it common in the earlier 60 chevy and gmc 1/2 and 3/4 tons with a 2 speed hydramatic in em. I paid 100 bucks for the entire truck I got this one out of :D The steering column setup is an ididt with a splined end and DD end for the newer sterring box also a salvage part from a 79 3/4 drilled out the plastic parts that cause it to collapse in a wreck and that allowed me to shorten it to fit my truck.

Re: 1964 GMC 3/4 ton build :D
 

Been looking at my fuel tank Idea and going to scrap it just too dammed big lol. &0 gallons for that truck yeah wonderful but the tank is going to interere with my rear view mirror setup. Here is what I am looking at now. Just a tad taller than the bed rails 45 gallon with fuel sender and line openings.

http://www.northerntool.com/shop/too...6745_200306745

Found a performance shop in north richland hills today texas that is a licensced GM performance parts dealer and factory mechanic gone solo to open his own shop, been open about 10 years, and has a full dyno. Prive for a custom built harness installed is 700$ for the l92 engine and 6l80e trans he said he can do the rocker switch for the manual mode and a tow haul button button as well to match up to my lokar shifter. Gonna be modifying the lokar shifter rod to work with the 6l80e since it has the same shift number as a 700r4 ie 5 position. the guy at the shop has computers in hand the E38 series and all the other goddies to make this engine run. He has a some bracket setups specifically for the 67 up trucks as well that are package deals.

here is the link to his site. He doesn't list the custom harness setups on there he told me about them on the phone today:

Re: 1964 GMC 3/4 ton build :D
 

That is too cool. I like it, all that computer is above my limits, but I like it. Thats gonna be one nice truck.

Re: 1964 GMC 3/4 ton build :D
 

12 year sin the painful decisions and building bu t I agree but then this is my baby. able to tow rice burners down the highway without hitting the gas pedal :devil:

sean

Re: 1964 GMC 3/4 ton build :D
 

well got the interior wiring harness layout finished today and quite happy with it. The new fuel injection wiring will be able to plug directly into the factory harness to provide power tach and speedo now :D.

Seam

Re: 1964 GMC 3/4 ton build :D
 

ok some more pictures of the interior where the harness is going :D got the harness in and tenatively routed atm. now just got to take another few hours to get the center section of wiring the right length for the neutral safety and eletric seat wiring the right length now :D then I get to strip everything back out for august when it runs up the road to the painter in whiteright texas. I am going to take the cab to him first so he can work on it while I finish the littler details on the frame. Looking at ways of lifting the cab off by myself with my engine crane just got to figure the right angles and chain lengths to lift it levelly then set it on a rolling frame work I happen to have the whels and the 2x6's for :D.
