1972 GMC "the beast" c20

[292farmer]

wow been a while since ive been on lol. been busy thought got a house for me and my wife and our son on the way! thats right im gunna be a daddy hes due march 24th and ive picked his name as Thomas Joesph James Smith. thats the main reason i wanted a house, but also so i have room to work on my toys . heres some pics of the house truck was on lawn for pics but i now moved it into the driveway to start my rear end swap.

[292farmer]

i picked up a GM corp 14 bolt for FREE! off my uncle its out of his 87 diesel 1 ton p/u. its got 4.10's and a locker! so im pretty happy its definetly an improvement over my current gearing gearing should see at least 2mpg inc. and im hoping 60mph will finally be attainable

[67chevy1series]

wow ,now that is an axle!

[292farmer]

yeah lol im not familiar with the later years so im guessing since its out of a 1 ton it is a full floater im just used to seeing hubs sticking out lol, im hoping this axle will provide better mileage as it has 4.11 over my current 5.13's but the addition on a locker may negate that, but we'll see. i hope to get the axle into my basement and on to my work table so i can pull drums off redo brakes and clean it up. i have to modify it to fit my coil spring susp.

[RCbowtie69]

looking good, keep up the hard work

[67chevy1series]

yes my truck originaly had 4 11 gears and a 327 so it was ready for the drag strip or haulin

[292farmer]

well the 14 bolt axle didn't work out turns out its a semi floater....but since we've had 48in snow in nh a local garage that had a flat roof, paid me 150$ each time to clean the roof 3 times, and i decided to trade that money for a rear end gear swap so the beast has 4.13's now!!! so much better then 5.13's
not that ive gotten the chance to drive it yet. no brakes...but! i got all my new parts this week(minus 3 coming tomm). cost me 170$ just for the two drums yuck. about 270-300$ total.
plus while at napa trying to get a price on a 1bbl carb, the owner instead refused to give me a price...but instead gave me free parts!! as in 2 1bbl carbs and a 261ciI6 3x1bbl intake and exh manifold combo. so i at least bought the 21$ rebuild kit off him for one of the carbs.
and i also got cliff ruggles quadrajet book and...the inline six power manual by lou santucci!!(still being shipped, grrr...) so long story short this build thread will be seeing lots of pics and typing in these next few days lol thank god i needed to search button my thread and i MISS DRIVING MY BEAST!!!

Congrats on the rear-end gear swap... and congrats on the soon-to-be daddy status! Life-changing event for sure. Hope all goes well.
Love what you are doing with your C20. Great to see your truck hauling hay and earning its keep!
I'm working on my '72 Cheyenne C20 and she was a farm truck most of her life.

[292farmer]

thank you! im very excited for the big day, ive been so busy lately building the nursery, and working on the new house that i havent touched my truck sigh...but im hoping to finish it in the next two weeks, my wife says if i get the exhaust quieter we can take the truck home from the hospital im keeping my fingers crossed. yeah the truck was bought as a farm truck and even if i get around to a full resto it still will get farm used lol. do you have a build thread?

[292farmer]

well got the carb rebuilt for the truck, hoping to get the fuel inlet, and fuel line for it today so i can get it on!

[67chevy1series]

kyle nice work! i like the shifter tip!

[292farmer]

yeah me too i got it installed to day and also cleaned out my basement to work on my 14bolt, its got a 4.10 case and locker and is a semi-floater? also cleaned out the garage...ie i shoveled snow down to the ground, if its warm enough tomm i'll start the rear brakes and the brake lines.

[292farmer]

and some more, of where the truck was and where i shoveled to work on it, oh and yes i know i need a truck seat

[292farmer]

and the truck parked in the "garage" as you can tell it was nite time by the time i finished, was a good days worth of work. oh and i found a use for the old shift knob, set it on pellet stove, once warm use like a massage stone on wifes back (our son is killing her back 5 more weeks!), wish i had a pic of her face when she realized she owed her thanks to my truck

[292farmer]

holy cow is it cold out! got truck jacked up and pulled the pass. tire, and drum off. wow is that drum worn compared to the new one like 12-7/16" worn over the new 12" size lol. and look at those cracks i wonder why i had trouble stopping

[eagleuh1]

Man, those sure are some terrible working conditions. I'd think your hands would freeze to the lug wrench.

[292farmer]

they might have if i stayed outside long enough! lol ive doing doing short spurts. course now im at a major road block, i pulled apart both sides, i knew the pass side brake bar lever was junk i was hoping to use the drivers side as a model to fab a new one. but the po or po's mechanic removed it! and no stores in town have them available as far as they can say they dont exist! so i dont know what to do...im hoping a 13in brake bar will fit with minor trimming as mine are 12in...idk

[292farmer]

for got pics but the other night i put carb on and started it up! found out the linkage hits the intake so it wont go below 2000rpms lol. choke seems to work though slowly. pulled the carb off today to grind intake down for linkage, and saw the whole intake had a puddle of fuel. thinking my floats were bad i pulled the carb top off the floats were good and still to specified level. fuel pressure is 3.5-4psi so not to much. im wondering if running at 2000rpms with choke on dumped so much fuel in the intake that it puddled from not enough air flow to move it to intake ports? or if thats what happens in 30* weather with no heat to intake?

[sbc383rulz]

yeah that is a semi floating 14 bolt, thats no locker either thats spider gears sitting in there. with you were closer i have a D60 3.54 gears sitting at my dads place. good luck wiht the baby! we just found out my wife is pregnant! truck looks good!

[Maxxd07]

X2 on the semi floater, it would have come out of a 3/4 ton from the 80s. The 1tons had a full floater in them. I know what its like working in them conditions since its almost March and we just had -28 this morning on the thermometer! Seen alot of them temps this winter. Build looks like fun and from the snow pics maybe a 4wd is in the works?

[292farmer]

yeah no locker i knew that but was still thinking locker as my uncle told me lol damn my brain. got some more brake work done today @ 29* lol im really wondering what the po was thinking looking at these brakes as he used wire ties! and it seems my coil spring wheels cyl dont fit. too big so im gonna try leaf spring ones, im hoping i assembled everything right as i got nothing to go off of grrr....

[lowbucktruck]

The old girl is looking good, farmer! I'm digging the headers and Thrush glasspacks on that truck, she must sound GOOD! I hope your wife is doing okay. I imagine you are busy with work and taking care of her.

Hey, I don't actually have a build thread, I'm way behind on that. Have to pull the heads off my baby and give em a serious valve job. Will post some pics soon.

[292farmer]

wow i feel like superman! lol well we had our son THOMAS JOSEPH JAMES SMITH on march 14th he was 8lbs 2ozs! hes been keeping me busy lol. finally got some time today after helping the father in law pick up his new washer and dryer.(got his old ones in return) to work on my truck i took off the bed so i can fix it up, and clean/paint frame post pics later

[292farmer]

and some more

[292farmer]

and the last, btw did i mention i was stupid and did this all alone? i think it looks kinda cool with no bed, im gonna make a wood flat bed for this summer so i can take my time working on the orig bed. plus im sure a wood bed is lighter and maybe i can pick up a mpg or 2 lol and i love the wrench i found rusted to the nut on the bumper bracket i smacked it with a hammer but it didnt budge!
