    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...

    454 bolt in ?

    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 ?

    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.

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

    454 bolt in ?

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

    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.

    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
