    Big Red: 1991 K1500HD

    We needed to get the timing right as the truck would randomly die while driving which is never good especially when your exhaust consists of long tube headers into 2 purple hornie glasspacks and nothing else. Timing was perfected after some trial and error. She was almost ready for the journey...

    Big Red: 1991 K1500HD

    We made the motor run on our first try, not too bad for 2 kids one without mechanical experience (me). Took a spray bottle poured some gas in it and ran a rubber fuel line to it. Carb would run off it not too bad. Later we ran all new fuel lines using 1/2 rubber hose from the gas tank all the...

    Big Red: 1991 K1500HD

    Me and my friend got the top end of the motor taken off cleaning and checking everything. We were very fortunate that we had a mechanic friend across the street that used to race circle track and build sbc for a living. He helped us from time to time on motor work, but mostly to tell is what we...

    That's terrible man, well I guess that's going to put me off of rebuilding a trans unless I need to

    454 bolt in ?

    454 bolt in ?

    Well thank you. I was looking at how to do a th400 swap as I'm pretty sure my 700r4 just took a crap on me tonight driving around and gave it full throttle for a moment. Second trans my truck has killed. TV cable was set right on my Holley carb with the geometry bracket and tight like a guitar...

    454 bolt in ?

    That's why I'm leaning towards it. Regardless I know I need a new crossmember for either transmission.

    454 bolt in ?

    How would that setup on a holley carb ? Wouldn't you also need said tbi computer be tuned or flashed for a 4l80e ?

    Yes my carb with no lock up doesn't like anything above 60, 70 max

    454 bolt in ?

    I would like a th400, so I may have to look into swapping one of them in, but would like OD so maybe a nv4500 swap in the future.

    454 bolt in ?

    Personal experience ? I'm just wondering have heard some mixed things

    454 bolt in ?

    I got a great deal on a 289 454 block. I've seen a bunch of post over trans will obviously not hold up, computer won't swap blah blah blah. Haven't really found much on if it will fit k1500 size wise and motor mount wise. Trans will be a built 700r4 from monster with 14 bolt ff so not too...

    Tire fitment

    Damn that truck looks way better than mine haha, I kinda liked the stuffed balloon look. I'm thinking if I crank and trim the rust on my fenders and a few inches on the bumper with spacers/offset wheels I think it should be fine.

    Tire fitment

    Yea I'm definitely having to regear as mine came stock with 3.42s.... but that makes me full a bit better that just with a trim and crank that 35s can fit

    Tire fitment

    Hey guys ! I was looking at upgrading my trucks tires to something more aggressive than the off brand ATs that came with it. I've been looking around and have decided on super swamper tsl sx tires. I want to run a 35" tire, but I want to run the 15.5" wide tire because the wider the tire the...

    Transfer case stuck in 4wd

    Will have to install front d shaft and check when I get a chance. Buddy's little brother was helping by putting fuses in, guessing he may not have put a good one in. I'll have to give it a shot when I get the time. Thanks for your time

    Transfer case stuck in 4wd

    So I changed the fuse on my 4wd and was able was able to get it to go into 4wd finally. Unfortunately it wouldn't come out so we tried putting in 4hi then to 2hi. Going back and forth between neutral and drive. And the 4wd light would stay on and the front driveshaft was still turning. We even...

    Skid plate question

    This may not be the right place for this but I didn't know where else it should go. I just had a question about mounting the front differential skid plate from a z71 truck onto a non z71 1991 k1500. I was given the skid plate by itself no bolts to speak of yet. Does anyone have pictures of how...

    Transmission Problems

    That's a good point. I've been looking at some shop manuals for our trans but just haven't gone through with tearing it down. Just scared of breaking something even worse haha

    Transmission Problems

    Ok thanks for the heads up. Found a local shop that'll tear it down and look it over for free, I just have to pull it back out lol

    Transmission Problems

    So you thinking since I already lost 3 and 4 that without adjusted my tv cable properly my trans may now be no good ? Or is there still some hope ?

    Transmission Problems

    Would it just stop working after a moderately hard acceleration ? I never set the TV cable, just got a stud for the 700r4 mounting hole on my holley carb. Could be a bad rebuild but it's a toss up.
