Caught a break in the weather today. Frame and rear end are blasted.

My kids came out to help me paint the frame today. The extra hands made short work of it. Hope to get it flipped over and the other side painted tomorrow. https://farm1.staticflickr.com/885/4...7ab5c7f2_z.jpghttps://farm1.staticflickr.com/876/4...0a7f8a80_z.jpghttps://farm1.staticflickr.com/810/4...98a4148e_z.jpg |

Looks fantastic! Its great to see kids smiling while working!!

Re: 66 GMC Long to Short LS Swap
Good stuff

Re: 66 GMC Long to Short LS Swap
Make sure you follow the re-coat "window" on the can - Tremclad wrinkles nasty if you re-coat at the wrong time.
(I painted my '77 with Tremclad and a roller - tee hee) |
Re: 66 GMC Long to Short LS Swap
Nice work so far. Joining in to see it to the end...

Re: 66 GMC Long to Short LS Swap
Got the frame flipped over, kids helped me paint the frame again while the dog supervised.
https://farm1.staticflickr.com/803/2...29f0c4ee_z.jpg Pressed out the old trailing arm bushings and installed some new polyurethane ones. Got the rear end painted and started putting the rear suspension back together. Using 5" drop springs and 2" drop blocks. So nice to be working with clean, freshly painted parts and brand new hardware. No more rust and grime!! https://farm1.staticflickr.com/877/2...f7502b22_z.jpghttps://farm1.staticflickr.com/868/4...92609b97_z.jpghttps://farm1.staticflickr.com/807/2...e560e6bb_z.jpg Painted the spindles and callipers and put the front suspension together. 2.5" drop spindle and 3" drop springs. https://farm1.staticflickr.com/898/2...11b4ac41_z.jpghttps://farm1.staticflickr.com/807/4...4c64ec21_z.jpg Good buy old drum brakes, hello shiny new disks. https://farm1.staticflickr.com/793/4...5f02dc20_z.jpg Up until this point everything had been great with this Grand Slam kit from CPP. Bolted up the front wheels and found that the rotor hub doesn't fit the centre hole on the wheel. From all the stories I've read about CPP's customer service I'm not looking forward to getting this sorted out. https://farm1.staticflickr.com/791/4...3fe75ca4_z.jpg Does anyone know what rotors I can use on the CPP spindles that will fit the stock wheel opening? I'm thinking it might just be easier to buy a proper set than deal with CPP and have to ship the old ones back. Bolted both front wheels up so at least its a roller now. I've got some major positive camber in the front. I'm doubtful that even removing all the shims will correct it. Anyone experience this with a 5.5" drop? https://farm1.staticflickr.com/889/4...df484ee7_z.jpghttps://farm1.staticflickr.com/881/4...162cc20c_z.jpg Still have to sort out the rear shock relocation and hook up the steering linkage but I think I'll leave that for later. Plan to tear down the LS and get the block off to the machine shop. |
Re: 66 GMC Long to Short LS Swap
Hmm..mine is the same drop and had to have a very large shim pack added to get back to normal? In fact I added longer bolts on the upper control arm and my alignment guy said I barley had enough bolt? So it would be nice if yours will balance out with just a small set? Otherwise I Dunno? Is it the caliper that won't fit in the wheel opening or the rim opening isn't centered on the disc bolt pattern? That would mean the disc bolt pattern was askew right? Always something! Let us know what you find out! Otherwise a lot done!!!! Cool that the kids are game for some work!

Re: 66 GMC Long to Short LS Swap
Started tearing down the 6.0 this afternoon. So far cylinders all look to be in good shape. Got stuck on the balancer, don't seem to have a puller that will work.

Re: 66 GMC Long to Short LS Swap
The wheels will work perfectly fine not resting on the hub - many aftermarket wheels have larger bores than the hubs they need to ride on, and they are fine.
Just tighten the wheel nuts progressively and evenly, since they are now lug-centric. This may result in some imbalance, but you will know once it's on the road. |
Re: 66 GMC Long to Short LS Swap
I agree that you can get away with being lug centric instead of hub centric. I've done it many times. There are no OEM 6 lug rotors that will work. You are stuck with 6 lug aftermarket rotors.
|
Re: 66 GMC Long to Short LS Swap
Thanks Skinny and Captain, never would have thought it was ok to be lug-centric. I might machine a spacer to slip over the hub on the rotor and bring it out to the proper size. I was already thinking about trying to machine a spacer plate so my stock wheels would clear the callipers. Might try to make one piece that solves both problems.

Re: 66 GMC Long to Short LS Swap
Well a busy spring and summer has kept me out of the shop. A few weeks ago I went to a local show and shine and came across this beauty which got me fired up to get in the shop again!!
https://farm2.staticflickr.com/1850/...d7dfc8ee_z.jpg Got the ball rolling again with a few small items. Cleaned up and painted the steering linkage. Installed the new power steering box and new steering components on the truck. Got the new front shocks installed as well. https://farm2.staticflickr.com/1889/...a26fe208_z.jpghttps://farm2.staticflickr.com/1841/...29c35e8e_z.jpghttps://farm2.staticflickr.com/1851/...aa17876b_z.jpghttps://farm2.staticflickr.com/1850/...58a30f48_z.jpghttps://farm2.staticflickr.com/1876/...0b85677d_z.jpg Finished tearing down the motor as well. In the process of cleaning up the block and getting rid of some rust before it goes off to the machine shop. https://farm2.staticflickr.com/1863/...74522213_z.jpghttps://farm2.staticflickr.com/1896/...3ffe81d5_z.jpghttps://farm2.staticflickr.com/1896/...86eaac6d_z.jpg |
Re: 66 GMC Long to Short LS Swap
Looking for some opinions on this kit from Summit for my rebuild. Looks decent to me but this is my first motor build.
https://www.summitracing.com/int/par...illocation=int |
Re: 66 GMC Long to Short LS Swap
Not sure if that kit would work with your cathedral ports. I thought you were just going to hone it and re-ring using your old pistons? What are your goals with the motor?
|
Re: 66 GMC Long to Short LS Swap

I had originally planned on re-ringing the old pistons but for the price of the new ones I figure i might as well replace them while i have it torn down. Goal for the motor is to make it solid, reliable, and wake it up a little with a new cam. |
Re: 66 GMC Long to Short LS Swap
Kit looks good, pretty much everything you need. You installing all the bearings and checking clearances? I always worry about buying a bunch of parts and showing up at the machinists saying, "help me", and I didn't buy from them. But maybe they don't care and are happy to just do the labour.
|
Re: 66 GMC Long to Short LS Swap
I'll be putting the motor together and checking clearances. Should be dropping the block off at the machine shop tomorrow. I would prefer to buy the parts through the shop but i doubt they will be able to match the price from Summit.
|
Re: 66 GMC Long to Short LS Swap
Anyone else following Duncan’s build, feel lazy?
|
Re: 66 GMC Long to Short LS Swap
Check Rock Auto too. I've found them to be cheaper than Summit, and local shops cannot touch their prices. Even with shipping.
|
Re: 66 GMC Long to Short LS Swap
I find with a lot of stuff from Summit that, once I do the dollar conversion, Mopac is bang on for pricing.
|
Re: 66 GMC Long to Short LS Swap
Got the block dropped off at the machine shop. Their prices are pretty good so I think I'll buy all my parts through them. Got to work on modifying the wiring harness using the info from LT1swap.com. Took a few hours to get all the old loom and tape off. Pulled all the unneccesary wires out of the harness.
https://farm2.staticflickr.com/1875/...82de205d_z.jpghttps://farm2.staticflickr.com/1892/...ffc784a7_z.jpghttps://farm2.staticflickr.com/1842/...6d4a7fa4_z.jpghttps://farm2.staticflickr.com/1891/...483352a9_z.jpg |
Re: 66 GMC Long to Short LS Swap
Dunkan, do you have a link by chance on where you got the information, looks like you have printed pages for pinouts as well. I've done a number of searches over there and just find people that are talking about doing a swap.

Re: 66 GMC Long to Short LS Swap
Finished work on the wiring harness for now. Not going to tape it up and put new loom on until i can lay it out on the motor.
Got the block back from the machine shop along with most of my parts. https://farm2.staticflickr.com/1920/...de116bcb_z.jpghttps://farm2.staticflickr.com/1979/...7f2a4271_z.jpghttps://farm2.staticflickr.com/1967/...65a37521_z.jpg I've built a ton of dirt bike engines, but this will be my first vehicle engine. I've been researching clearances on these motors. Crazy how much conflicting info there is out there. Decided to use the clearance numbers i got from the machine shop. after cleaning the block I got the mains installed. Checked the clearances with the plasigauge, and then with a mic and bore gauge. I didn't find the platigauge very accurate or consistent. https://farm2.staticflickr.com/1930/...7e9e0c24_z.jpghttps://farm2.staticflickr.com/1969/...4b6cde74_z.jpg Installed the crank and torqued down the main caps https://farm2.staticflickr.com/1921/...98917388_z.jpghttps://farm2.staticflickr.com/1955/...0a521ec9_z.jpghttps://farm2.staticflickr.com/1949/...8c746d49_z.jpg Cleaned up the old pistons and rods, and pulled the old rings off. Picked up a new sleeve of platigauge. Got the new rod bearings installed and checked the bearing clearances. I got much better measurements this time. https://farm2.staticflickr.com/1914/...28729f55_z.jpghttps://farm2.staticflickr.com/1905/...0e095787_z.jpghttps://farm2.staticflickr.com/1917/...b338a944_z.jpg Checked the ring gaps and installed the new rings. Got one bank of pistons and rods put in. https://farm2.staticflickr.com/1921/...baa59eeb_z.jpghttps://farm2.staticflickr.com/1933/...e03c995e_z.jpghttps://farm2.staticflickr.com/1951/...5fe8bf15_z.jpg |
Re: 66 GMC Long to Short LS Swap
Looking great man. Any plans for boost?
|
Re: 66 GMC Long to Short LS Swap
No plans for boost. Just not in the budget right now with all the other stuff i still need for this build.
|
Re: 66 GMC Long to Short LS Swap
Did a little more work done on the motor. Finished installing the other bank of pistons and rods. Lubed up the new Comp Cam and slid it in place. New billet roller timing set, and a high flow Melling oil pump.
https://farm2.staticflickr.com/1977/...a6d60960_z.jpghttps://farm2.staticflickr.com/1966/...de5ac532_z.jpg Taped up the block and hit it with a coat of rust converter followed by a few coats of Chevy Orange. Painted the front and valley covers as well. Buttoned up the bottom end with a freshly hot tanked oil pan. https://farm2.staticflickr.com/1940/...155dab85_z.jpghttps://farm2.staticflickr.com/1980/...c91677bf_z.jpg[/url]https://farm2.staticflickr.com/1947/...93d5826f_z.jpghttps://farm2.staticflickr.com/1965/...f6fe545d_z.jpg |
Re: 66 GMC Long to Short LS Swap
nice progress on the project ...

Re: 66 GMC Long to Short LS Swap
Keep the updates coming

Re: 66 GMC Long to Short LS Swap
Nice build! Depending on how low you are you may consider an f body oil pan for your set up. The truck pans hang a bit low for my comfort on a lowered truck. Also, curious if that's a boyds welding fuel tank you webt with, and if so, how low it hangs below the frame?
