Hey everyone! Just thought I'd drop a wee introduction, as I'm beyond happy to have found this site--ten minutes of perusing the forums has already given me some good ideas for my little project.

A bit about me; I'm 25, and this is my first vehicle that I've actually owned--as in, I bought her, I fix her, I have my name on the title, and it's awesome. I grew up with a Chevy/GMC-Lovin' father who had nothing BUT square-bodies, and use to tell little 9-year-old-Me, "This truck is gonna be yours some day," while pointing at a monstrous 1970-something Chevy 3/4 ton with a long bed, crew cab, and duallies. Now I never got THAT truck, but once I was able, I went and found one of my own!

Now enough about me; my Trusty Steed is a 1976 GMC Sierra 1500 4x4. Shortbed, stepside, 4.1L 250ci In-Line Six. 4-speed Manual Muncie SM465 Transmission ( Or is it 3-speed with Granny? One of those! ) I actually bought this truck from my uncle who had dropped around a grand on it, drove it home, then let it sit for around six months without touching it again. At the time I was buying a '74 Chevy Cheyenne 3/4 ton off him for payments, and we just made a clean swap back, he gave me the GMC for the "Price" of the payments I'd made so far. He got the '74 back ( his favorite pickup he'd owned, it had just broke down, so he sold it to me on the cheap, and I fixed it! ) and I got my dream truck--manual trans, stepside, all yes.

The fellow my Uncle bought this truck from passed away unfortunately mere weeks before I took the truck, so I was never able to ask what all he'd done to it, so it's history is mostly a mystery aside from what I can visually see, or what's on the title. It came with no glove-box, and therefor, no documents, and the only thing I ever found in the truck was some kind of knife under the seat ( cool, I s'pose?! )

It's a Project--she's bent, bruised, and broken in places, but the engine is MINT, she handles like a ( very bumpy, grumpy ) Cadillac, but we're workin' on it!

At the immediate moment, she's actually my work vehicle, too -- I deliver food locally, and I get more then a few compliments on my choice of workhorse. In the summer, it's a bit overkill--gas isn't too bad, with the in-line six, but still. I don't like using her as a "beater car" for work. But in the winter, my bosses are thanking the Pizza Gods when I show up for work and it's a blizzard outside. :)

And yes, I nicknamed her "Bad Jack" -- despite that itty-bitty engine, she has some serious bite.

Welcome from Maine! There's not too many of us rocking the inline 6, but a few here. Two biggest suggestions for the 250, upgrade the dizzy to HEI if not already, and swap out the monojet for at least a 2 barrel carb. Oh, and if you like a really nice burble, throw a glass pack / cherry bomb on that like I did!

@CSFJ; Thank you! I get a couple of compliments on that, and haven't seen another close to my year that has it in my town!

@Geektrucker; I've been told by a couple people I know, "Upgrade to the 350!" and I honestly kind of like my wee little In-line six, haha. Already gonna do the HEI upgrade and the Carb. Sawed the exhaust off a couple months ago, and will probably be throwing a cherry bomb on it, though I have a Flowmaster lying about that I might try out. With three foot of snow outside, progress is slow, but by the end of next summer she'll be like a whole new truck!

@Georgeb; Thank you!

Don't do the downgrade to the 350! I say downgrade because earlier in life I had an '84 GMC heavy duty K20 8600 GVW with the in-line 292. I thought I needed more power and had a guy build me a 350 sb, worst mistake ever. Poor truck eventually went through 4 350's, eventually ending with a Jasper engine that pumped oil into the breather canister. My wife finally had a enough and said to trade it off. I did, for a'90 F250 with the 300 6 cylinder. Best truck I ever owned as far as dependabilty. I feel I ripped the heart right out of my GMC and won't ever do a downgrade again.

Thank you, everyone, for such a great welcome! I love it here already ;3
@77 K20; Well hey there! I was hoping there were some of us Mountain-Folk 'round here ;D
@crpntr78; I'll probably leave it just as it is! Though hopefully no one can fault me for upgrades some bits here and there ;D I'm not a huge fan of putting a 350 in it, as I had the '74 with the 350, and I appreciate the gas mileage of my wee In-Line, haha.
