Re: 66 GMC Long to Short LS Swap
Got my heads back from the machine shop, had them vacuum tested, tanked, and decked. Installed the new seals and dual springs
https://farm5.staticflickr.com/4813/...5bdd57f5_z.jpghttps://farm5.staticflickr.com/4894/...996efc1e_z.jpg I blasted and painted the water and power steering pumps, all the pulleys and brackets and got them painted up and mounted. Dropped in some new lifters and bolted the heads on. https://farm5.staticflickr.com/4908/...c783dfcb_z.jpghttps://farm2.staticflickr.com/1954/...f16361ca_z.jpghttps://farm5.staticflickr.com/4894/...ce56ce3a_z.jpghttps://farm5.staticflickr.com/4870/...6bbccd16_z.jpg Blasted and painted the motor mounts https://farm2.staticflickr.com/1928/...eae349b0_z.jpghttps://farm2.staticflickr.com/1955/...3ed3072a_z.jpg Coat of paint on the transmission as well https://farm5.staticflickr.com/4868/...4050c95d_z.jpg At this point the engine is pretty much button up. Still need to clean up the coils and brackets and throw the intake on. Also planning to get the alternator shell blasted and painted. |
Re: 66 GMC Long to Short LS Swap
Looking good.

Looking good. I have the same mount plates and I'm thinking of using the I6 perches as well. Are those the Energy Suspension poly mounts? What location do you have them bolted to the plates?

Re: 66 GMC Long to Short LS Swap
Slow progress lately. Pulled the motor and trans back out to swap mounts. Ended up getting the trans rebuilt while it was out. Cleaned up and painted the coils and brackets and threw on some new plug wires. Motor is back in and intake on. Just have to clean up the fuel rails and throttle body.

Got the passenger side floor finished and started fitting up the rocker. Hung the door so i could get the gap right. https://farm8.staticflickr.com/7846/...d4ff4702_z.jpghttps://farm5.staticflickr.com/4899/...91f864c7_z.jpg The bottom of the back wall of the cab is rusted out. I wasn't sure exactly how I was going to tackle this repair until I came across a guy giving away a full back wall. https://farm5.staticflickr.com/4902/...42907473_z.jpghttps://farm8.staticflickr.com/7902/...8d7847b8_z.jpg |
Re: 66 GMC Long to Short LS Swap
Looking for my weekly fix...

Re: 66 GMC Long to Short LS Swap
Cool build. Lots or good work going on here!
|
Re: 66 GMC Long to Short LS Swap
Here ya go Notch!
Moving along with the rust repair. Made a pile of relief cuts, did a lot of bending and hammering. Rocker is all fit up ready to weld in. Going to wait on that until I get the cab sand blasted. https://farm8.staticflickr.com/7891/...8b08010a_z.jpghttps://farm5.staticflickr.com/4821/...ff1033fb_z.jpg Finished a bit of work on the passenger floor. Had to weld in a small sliver from a previous crappy fit up. Replaced a piece of the trans tunnel hump as well. https://farm5.staticflickr.com/4898/...fd1fc2dd_z.jpghttps://farm8.staticflickr.com/7863/...47267f0c_z.jpg Moved on the the kick panel firewall seam. Drilled out all the spot welds and made a template for what i wanted to replace. https://farm8.staticflickr.com/7806/...60435bbd_z.jpghttps://farm5.staticflickr.com/4888/...c74240dc_z.jpghttps://farm5.staticflickr.com/4861/...dceb990f_z.jpg Transferred the template to some 18g and cut it out. once i was happy with the fit I cut out the kick panel section. https://farm5.staticflickr.com/4862/...4d1a1e75_z.jpghttps://farm8.staticflickr.com/7820/...1219f0ae_z.jpg Made the bends for where the fire wall gets spot welded to the kick panel. Fine tuned the fit and its ready to weld in. https://farm5.staticflickr.com/4897/...b3ea3ec5_z.jpghttps://farm8.staticflickr.com/7828/...42bfac84_z.jpghttps://farm5.staticflickr.com/4891/...c8c7d354_z.jpg The inside of the door pillar was pretty rusty. Found a rust encapsulator product from Eastwood with a long hose and 360 Degree nozzle. Shoved it up the pillar and coated the whole inside top to bottom. Will let that cure overnight and start welding in the kick panel patch tomorrow. https://farm8.staticflickr.com/7811/...dda609f0_z.jpghttps://farm8.staticflickr.com/7833/...4c23fd2a_z.jpg |
Re: 66 GMC Long to Short LS Swap
Nice job on the metal work!

Re: 66 GMC Long to Short LS Swap
Yes lots of metal magic on this one! Very nice!

Re: 66 GMC Long to Short LS Swap
Slowly chipping away at the rust repair. Finished up the kick panel and started on the firewall.
https://farm8.staticflickr.com/7859/...2634e069_z.jpghttps://farm8.staticflickr.com/7854/...d29e89e8_z.jpg Built a sandblasting cabin and wheeled the cab inside. Started blasting the cab to see what was surface rust and what needed to be cut out. I was really happy to find the areas above the windshield were not rusted through and cleaned up really well. The lip that the windshield seal goes around is a different story though. That is gonna suck to repair!! https://farm8.staticflickr.com/7867/...423f9beb_z.jpghttps://farm8.staticflickr.com/7850/...585f45e0_z.jpghttps://farm8.staticflickr.com/7895/...971341a3_z.jpg Back onto the firewall/floor seam. Got most of the remaining pieces made and fit. Hopefully will get time to them all welded in this week. https://farm8.staticflickr.com/7823/...ec0319c7_z.jpghttps://farm8.staticflickr.com/7810/...1d983bc0_z.jpghttps://farm5.staticflickr.com/4813/...7fd1ea73_z.jpghttps://farm5.staticflickr.com/4810/...3a2da325_z.jpg |

Re: 66 GMC Long to Short LS Swap
How effective are you finding that sand blaster, and what size is your compressor?

Re: 66 GMC Long to Short LS Swap
Is that a PA blaster as well?
I was planning on taking everything to "the man" and have them blast it all, but I really need to deal with the rust inside everything I have to cut out (like the rockers, corners, etc. etc.) What HP and CFM is your compressor? |
Re: 66 GMC Long to Short LS Swap
My booth is pretty simple, just a 2x4 frame 10ftx10ft, 8ft tall wrapped in poly. I didn't really seal it up too much, just wanted to keep the sand from getting all over the shop.
Blaster is Princess Auto, I run a couple dryers inline to the tank. This is the compressor https://www.aircompressorsdirect.com...ssor/p705.html |
Re: 66 GMC Long to Short LS Swap
Oh, good to know. I have the same compressor (KMS Tools jobbie). I may wait for a sale at PA then, for the blaster.
|
Re: 66 GMC Long to Short LS Swap
Impressed with your progress on the metalwork! Great idea with the enclosure for the sand blasting. Good solution on the outer rear of the cab (finding a new back for it). I have a similar issue. Was thinking I should buy a shop press, create a press brake, and make the bends in sections. The other solution I was thinking about was maybe a bead roller with a tipping die.

Re: 66 GMC Long to Short LS Swap
did you use the eastwood rust encapsulator on your engine block?

Re: 66 GMC Long to Short LS Swap
Passenger floor is all finished up
https://farm8.staticflickr.com/7830/...365b640c_z.jpg Cut the bottom off the back of the cab, its all rusted from the inside out. Started cutting the back of the floor out to be replaced. Also removed the drivers side rocker. https://farm8.staticflickr.com/7902/...11b71566_z.jpghttps://farm8.staticflickr.com/7907/...4cc1e65a_z.jpghttps://farm8.staticflickr.com/7878/...b29bec1f_z.jpghttps://farm8.staticflickr.com/7918/...7b0828fc_z.jpg |
Re: 66 GMC Long to Short LS Swap
Replaced the drivers side rear door pillar bottom with a piece I cut out of a donor.
https://farm8.staticflickr.com/7924/...6defa6e7_z.jpghttps://farm8.staticflickr.com/7919/...25138db7_z.jpg Blasted the back side of the cab and floor and started on replacing the rotten metal on the back of the floor where it meets the cab. https://farm8.staticflickr.com/7839/...5615c25d_z.jpghttps://farm8.staticflickr.com/7822/...0f351914_z.jpg |
Re: 66 GMC Long to Short LS Swap
Wow man, love to see you still making progress and not getting discouraged with all the rust repair. Keep it up!
|
Re: 66 GMC Long to Short LS Swap
Thanks Notch! For a while there I kept thinking "what am I doing here, just find a new cab". Was a little overwhelming at first but I have learned a lot as I go. I just keep plugging away, little by little. I feel like have the worst of it behind me. Drivers side should go a lot smoother. Glad I put in the work to save this old truck.
|
Re: 66 GMC Long to Short LS Swap
Replaced a bit more of the back of the floor pan. Had to cut another section off the back to get access to make the repair, then weld it back in
https://farm8.staticflickr.com/7825/...0b36d24b_z.jpghttps://farm8.staticflickr.com/7816/...9d7423ed_z.jpg Sliced the bottom back off the donor cab. Drivers cab corner is pretty good, but not so much for the passenger side. https://farm8.staticflickr.com/7898/...b613afe0_z.jpghttps://farm8.staticflickr.com/7922/...a6bced9a_z.jpg My original plan was to use a whole replacement cab corner, but after comparing it with the original I could see it was going to be a lot of work to reshape the replacement. I decided to use the one from my donor. I knocked out a bunch of dents and used a small piece from the patch panel https://farm8.staticflickr.com/7903/...ae75e424_z.jpghttps://farm8.staticflickr.com/7913/...f31444f3_z.jpghttps://farm8.staticflickr.com/7922/...a6bced9a_z.jpghttps://farm8.staticflickr.com/7913/...11fe899f_z.jpghttps://farm8.staticflickr.com/7842/...3d7b19a3_z.jpg Hung the door and fit up the rocker. Started fitting the cab corner. Have to drill some holes for the spot welds and it will be ready to weld in. https://farm8.staticflickr.com/7844/...6eb860d2_z.jpghttps://farm8.staticflickr.com/7825/...cd00fe68_z.jpg Fit up the drivers side cab corner and the rest of the back. Looks like it will work well. Have to wait until I have all the drivers side floor and braces done before I weld this stuff in https://farm8.staticflickr.com/7832/...b5f4fbe2_z.jpg |
Re: 66 GMC Long to Short LS Swap
Sucks the re-popped stuff is that far off. Lots of extra work sometimes....
Impressive effort on your part for sure! |
Re: 66 GMC Long to Short LS Swap
Great progress Duncan.. keep up the great work
|
Re: 66 GMC Long to Short LS Swap
Cab corner is welded in. Started working my way across the back of the cab. There is one small section that I couldn't salvage from the donor that I will have to fab.
https://farm8.staticflickr.com/7914/...0a9a4dee_z.jpghttps://farm8.staticflickr.com/7919/...824372be_z.jpghttps://farm8.staticflickr.com/7905/...80d555a9_z.jpg While I was welding along the back of the cab I ran into a pocket of aluminum which instantly melted and made a mess. No idea how or why it was there? https://farm8.staticflickr.com/7920/...c9072a4a_z.jpghttps://farm8.staticflickr.com/7871/...441e443e_z.jpg |
Re: 66 GMC Long to Short LS Swap
That was most likely lead from an old repair back when lead was used. Nice work on the panel replacement and welding :thumbs:
|
Re: 66 GMC Long to Short LS Swap
wow great job but that led is a bummer it will be another education for us to learn how many ways to fix that? what's your choice. cut it out past the led? won't the led contaminate the steel where it's tined to weld or the steel to thin if you grind to far. iv seen led .25" to 10" wide depending on who did the work not the work needed. Thanks for the story,the pictures,and the time.

Re: 66 GMC Long to Short LS Swap
Well I ordered all the patch panels to start working on the drivers side floor, pillar, kick panel, fire wall. After waiting three and a half weeks they finally show up and the floor pan is wrong, so back it goes and I'm waiting again. In the mean time I finished up the last piece on the back of the cab.
https://farm8.staticflickr.com/7827/...d2688d4f_z.jpghttps://farm8.staticflickr.com/7833/...23f68405_z.jpghttps://farm8.staticflickr.com/7803/...8d23f313_z.jpg The area above the windshield where the seal sits is rotten on my cab. I've been searching for good deal on a cab to cut up and use to repair that area. Finally found one suitable for the repair, ended up getting a set of fenders as well. My fenders were beyond repair. Didn't really want to use repop's so I was happy to find this set. Small patch panels on the bottom and they will be good to go. https://farm8.staticflickr.com/7876/...6d63b364_z.jpghttps://farm8.staticflickr.com/7891/...704307b5_z.jpghttps://farm8.staticflickr.com/7858/...16a3b8ec_z.jpg I've never been a fan of the GMC gauges, and since the donor cab is a chevy I decided to swap dashes. This will let me use the Dakota Digital set up. Got the GMC dash removed, will be able to take care of some rust that would have been impossible to get to with the dash in. https://farm8.staticflickr.com/7896/...acd033dc_z.jpg My cab hasn't been in good enough shape to move since I installed the LS into the chassis so I haven't been able to check that the cab fit. I dropped the donor cab on the chassis to save space in the shop. Motor has tons of clearance to the firewall, probably 2 1/2 inches plus. I think it looks kinda funny, would look better tucked back into the firewall a bit more. What do you guys think? https://farm8.staticflickr.com/7820/...c506823b_z.jpghttps://farm8.staticflickr.com/7915/...5522928b_z.jpg |
Re: 66 GMC Long to Short LS Swap
The farther back with the engine as you can is better for weight distribution.

Re: 66 GMC Long to Short LS Swap
While I agree with Captain, yours looks to be the same place as mine. Truck drives fine, but I have not driven it much and not at all over about 40 mph...
You can see it here in Post #67, not the best picture but looks about the same distance as yours. http://67-72chevytrucks.com/vboard/s...=726351&page=3 |
Re: 66 GMC Long to Short LS Swap
I like your commitment to what should be.

Re: 66 GMC Long to Short LS Swap
Truck time has been pretty limited lately but I keep plugging away bit by bit. Finished up the rest of the drivers floor and the cab braces. Had to remove the gas tank bracket to fix some rust underneath. Coated inside the existing braces with rust encapsulator.

Also cut out the area above the windshield to be used as a patch panel for my cab.

Going to rebuild the rear end with a posi carrier, new ring and pinion, and all new bearings. Adding a rear disk brake kit from CPP. |
