    FINALLY installing vortec 350. Mechanical fuel pump?

    Just saw your post. Might hook it up and see like u said. Id preffer mechanical myself as it was originally that way and the only thing holding me back is the cam lobe. But again 12-20 is cheap i might need to invest in that. Sent from my SM-G920V using Tapatalk

    FINALLY installing vortec 350. Mechanical fuel pump?

    Ive thought about doing this, but if there is no lobe would it be possible for the pin to go too far and fall inside the motor? Sent from my SM-G920V using Tapatalk

    FINALLY installing vortec 350. Mechanical fuel pump?

    So that i dont have to get a new fuel line or adapters or whatever. I figured id leave the hard line from the carb to the pump since i am putting an electric pump inline near the tank. Other wise i need an apapter to the hard line or get a new hose to go to the carb. I had just heard of people...

    replacing add a leaf with lift springs. HD or ez ride?

    I probably will stick with the 2 inch lift springs as i will leave the add a leaf in the back for the time being. Dont want cali lean or as they say here carolina squat. Im thinking about loading the front of the truck and estimating the current spring rate and getting what is close to/ just...

    replacing add a leaf with lift springs. HD or ez ride?

    Long time no see fellow squarebody aficionados!! My truck is back in action, and my tuff country 2" add a leaf lift in the front has had it. A centering pin is loose on one side plus the front springs never rode very nice (had bad stiction and squeaks). I figured I would go with tuff country...

    torque converter lockup not working

    good to know! yes i have cruise. its not working now cuz i dont have all the vacuum hoses connected, but was fully functional before. If cruise control works, then this would not be the problem correct? All I need to do is put a hose to the vacuum reservior to test, the rest is still there...

    torque converter lockup not working

    Yea, this is the sort of thing i was looking for. I believe ive heard that before but had forgotten... Does anyone have a diagram of the whole system? not inside the trans but the external parts? is it just the brake switch and vacuum switch? ...or is there more? Heck I don't even need a...

    Led conversion?

    http://www.gmsquarebody.com/forum/showthread.php?t=2640&page=7 start here. Theres a helpful diagram I made for those like you who want to convert. I learned in hindsight that you shouldn't have to use load resistors like I did. I used an electro mechanical flasher unit (stock is mechanical). A...

    Led conversion?

    I've done a full led conversion, should be in my build thread. And I do mean a FULL conversion. The side markers require current to flow both ways. Leds only allow current to flow in one direction. it is not a plug and play procedure. you will have to wire up a relay (as I have) or make a full...

    torque converter lockup not working

    OK. do you know what fuse the system might be using? also, should directly conecting the leads at the vacuum switch reveal if the problem lies in the transmission? (neglecting the fuse and connections themselves as sources of the problem) maybe Im overthinking it, but I've been a bit confused...

    torque converter lockup not working

    oh right on the inside of the transmission. Yea i was hoping to check all external possibilities first before I go tearing apart my tranny. is the vacuum switch the only external component that might be faulty? Also, this tranny is the stock one in my 86. It was the year that the carb had...

    torque converter lockup not working

    Ah yes forgot to specify, but yes its a 700r4. So the wires will always be hot when the ignition is on? Also which fuse would that be? I checked the fuses and none of them seemed to make sense by name, I figured it might not be fused..

    torque converter lockup not working

    Hello all, I've had trouble with torque converter lockup for some time now. I've gotten it to work again in the past, but never seemed to be functioning right. When it locked up, it wouldn't unlock unless I got the trans to downshift. In 4th gear it would be locked no matter what, and the engine...

    Stuck choke/spark plug gap

    well, I feel stupid. Turned out its just the fuse. I guess I was assuming that since the choke light was showing, that the circuit couldn't have been broken. Youre right it is kinda screwy but definitely a learning experience. I was checking everything but the fuse, but atleast I learned a bunch...
