    Because building a carbureted 350 or an LS swap offer more power for the labor than a TBI 454. A TBI 454 is going to require just as much, changing the computer, altering the harnesses, so on and so forth. Although granted if we’re talking about building a carbureted 454, sure that’s different...

    Either build a proper carbureted 350 or do an LS swap. That’s pretty much the two paths you’re going to see recommended. A TBI 454 isn’t worth the work. If you’re going to do that much work already you’re going to see more gains from a purpose built 350 with a carb or an LS...

    NV4500 Odd Pedal behavior

    Thanks! Last night I greased the fork ball/pivot using the zerk on the bell housing. Also greased the bushings for the clutch pedal. So far today it’s all been like butter, but it’s been intermittent all along so if it shows up again I’ll just bite the bullet and yank it. I’ll update...

    NV4500 Odd Pedal behavior

    It’s push style yes. I haven’t had a chance to try bleeding it. I know they come pre-filled and sealed, not to be bled- not sure if that speaks to whether they are easy. It’s just odd. Drove it tonight and it was fine. Went into several lots, backed up, went forward in low and also 1st, smooth...

    NV4500 Odd Pedal behavior

    Hello everyone! Recently picked up a 94 heavy half 4x4 with a NV4500 transmission (factory, not swapped). I’ve googled high and low but I just can’t find something that fits the issue I’m having. The pedal binds pretty badly as you near the end of travel. It’s smooth and then the last inch or so...

    Need Help identifying a transmission wire 93 K1500 auto

    Sorted it out. It is indeed due to a swap. The harness for the original 4L60E was hidden in the frame. I knew that you could get a 700R4 or the E in 93, was just assuming that it had a 700 from the factory as a harness was nowhere to be found and the TV cable looked factory. Someone swapped in...

    Need Help identifying a transmission wire 93 K1500 auto

    Found it, as well as a broken connection in the wiring that was just electrical tapes together. Properly fixed and now the speedometer and odometer are live! Different topic but related to the transmission, do any of you have experience diagnosing a code 59? Showing trans temp sensor voltage to...

    Need Help identifying a transmission wire 93 K1500 auto

    Thank you! Yeah, it has some wiring issues (mostly with the lights but also odds and ends like this) but for the price and as rust free and straight as it is I couldn’t pass it up. Once it’s sorted out I will absolutely post what I find if someone else doesn’t have the answer here first! Could...

    Need Help identifying a transmission wire 93 K1500 auto

    Hello all! Looks like a great forum here. Just picked up a very straight K1500 extended cab for a great price. Needs some odds and ends done and has a few wiring issues with the lights. While starting off trying to eliminate bad or missing grounds, I was under the truck and found this single...
