77 yellow gmc swb
2 Attachment(s)
First off I have to say thanks to all the group members very nice gathering of trucks, I've been truck drunk for the last 2 weeks since I joined !
Well heres my project a 77 gmc I have had for about 15 years , it was all still factory when I bought it other than it had aluminum slots on it , it was starting to rust in the normal spots , I drove it for 5 years it even made 2 trips from Oh to Fl and back , I parked it because it was getting rusted out bad after 5 years it was time to either fix it or scrap it, I just couldnt part with it ,So here is a pic from as far back in the begining of the project as I could find by that time I already had the cab repairs and the 4 link done ,i picked up a bed in Alabama , doors were from a local ebayer ,it has cheap fenders on it and a harwood hood that I replaced later on with gm fenders and a goodmark hood , I put bags on the front and rear , turned the 454 into a 496 , back dated the front end to look like 73-74 , I'll try to just post pics of how I got to where it is now |

before the bed went to the body/painters I had it along with the cab and doors media blasted , it takes it down to nothing and left a freshly stamped looking part , the front of the bed still had factory markings on it ! after the body work was done he sprayed on the 4 coats BASF R-M base mixed up to the factory GM53 colonial yellow followed by the 4 coats of R-M clear , it turned out great ,

Re: 77 yellow gmc swb
Thanks guys , they used plastic pellets , a guy that works at the shop does it on the side , it works great for removing paint but wont take off any rust

ok after the bed was painted we started on the cab , I repaired the floor rockers and cab corner ,I filled in the holes for the a/c unit to put just a heater box out there , I didnt notice till after blasting that above the front window rotted away for about 30" across an 2" up so I made a patch and repaired it also ,I should have scrapped this cab but for some reason I fixed it ,

Re: 77 yellow gmc swb
after the cab was cut in, we mounted it up an the chassis and got the front end tuned up , I had to get a goodmark steel hood the body guy would work with the glass harwood hood , I knew it didnt fit well so I agreed to buy the goodmark it fit good for the most part

Re: 77 yellow gmc swb
Nice work man. I am converting my cab from AC to Non-AC as well. Just out of curiosity how did you go about cutting the hole for the heater box in the correct place?

I had to get the big block ready to go in next , it had been run and was fine with 781 iron heads but I changed them at this point to alm. heres a run down of what all the 496 is , I started with a .060 over 454 block,changed the rotating assembly with a 4.25" stoke crank , .250" longer rods and keith black #kb284 9.5:1 pistons, the cam is a Comp # CL11-254-4 , I bought a set of gm performance aluminum oval ports (same head that the zz502 has) changed the springs out for the comp cam # 930 springs that were for the cam, push rods are .100" long with roller rockers,I shaved em down smoothed the ports out a bit and stuck them on ,the intake is a edelbrock airgap with a 850 vacuum sec holley ,

I finally got it back to moving under its own power in these pics , got the fuel tanks I made at work, heater installed ,stainless brake booster and aluminum master cylinder from CCP are finally on for the final time! the alm master cylinder is chrome plated I tryed to get a plain 1 but they wouldnt do it , the chrome is good but the polish job before it has some bad grinding marks in the lid, may see if I can have the top powder coated ??

off to final paint pics , I'm glad I'm about done typing for today ! after paint and buffing , I put the headlight buckets in the NOS bezels I searched for 2 years to find in the local online paper classifieds ! a buddy found me a complete core support from a 73 so I robbed all the grill mounts from it and cut ,bent and welded the 2 middle brackets to fit on the later style flat supports, I added the nos gmc letters and tuned up the 454 emblem, from the used grill I got from ebay ,thats where its at today , I'm waiting on the 7 and 10 " ralleys to get back from the powder coater and a cover to keep the dust off it so i can take it to the fab shop I work at to finish the final assembly , I still have a long way to go and I'll be snoopin around to get some good ideas of what you guys did, if I would have found this group a long time ago I would have done some changes along the way I'm sure ,

Re: 77 yellow gmc swb
Is that the original grille or an aftermarket repop?
|
Re: 77 yellow gmc swb
I would say it's a stock grill off of a 73 GMC. I used to own one my self. After restoring it.. had to sell it, then moved on to dad's 68 GMC
