    Any experience with GMB water pumps?

    My cheap *** parts store water pump is leaking between the pump and backing plate, same way the oem pump did. Ive already got a cart built up on summit, so in the interest of some free shipping i figured id go ahead and get a pump from them. All they've got is this GMB stuff and Milodon...

    Baffling A/C clutch issue

    Clutch will engage when hooked directly to 12v source, i.e. A battery charger, but will not come on when plugged up to the truck harness. Getting 12v at the plug with A/C turned on at the dash though. Very confused.

    Finally getting things done

    Have spent the better part of the summer flipping bikes, so very little time spent on the lightning. After months of guilt im finally making headway. Got the frame notched, and new upper shock mounts to correct the ridiculous horizontal condition. I removed the slapper bar and two half...

    Rear shock mount options

    Heres the rundown. C-notch plates are in the process of going in. I had intended on retaining a small portion of the factory support plate on the outside of the frame rail, only the 5 inches or so that the shock mounts are riveted to. However, the rust between the plate and fame was awfull...

    Battery tray bolts

    Had my battery tray powder coated today but I've lost the hardware for it. Does anyone know the size and thread pitch for the three bolts that attach it? Battery is temporarily going back to the engine bay while I'm putting on the long bars and getting the Holley system situated

    rolled fender strength?

    can anyone comment on the strength of stock rolled fenders? Im concerned that the lack of the bend in the fender will result in a really flimsy piece of metal. like the difference between an I beam and a square bar, will the lack of a 90* bend result in a weak piece? i know i will need to roll...

    87 octane at 14*

    Just wanted to weigh in on this. For a long time i was under the impression that 14* on a stock engine was simply to much advance to run 87. Then here recently, guys start comin out of the woodwork sayin they run 87 without mishap. So im happy to say i tried it and the truck runs pretty much the...

    Crazy volt gauge

    My stock volt gauge is acting crazy. It will occasionally sit and vibrate rappidly. Not crazy bouncing across the spectrum, just kindof jiggling. Usually if i kill it and restart it will stop. I know my grounds and cables are good, voltage is good everywhere so its only happening to the gauge...

    275/55-17 or 275/50-17

    is anyone running either of these two sizes on a lowered truck? if so i request pics. I'm afraid that even with rolled fenders the 55's will be real tight on the front, but i think the 50's will be to short. thanks in advance.

    front tires for stock wheels (wide!)

    im contemplating getting rid of the torque thrust wheels and putting some fat tires on the stock wheels. There are a few options from M and H that i think will work fine for the rear, and they have 275/50-17's that are a good size for the front, but i have reservations about using a drag radial...

    rag joint location

    do our trucks have a rag joint? I've still got to much slop in my steering wheel but it seems that there is nothing else that could cause it, unless theres a rag joint in there that I've never seen....

    408 sound

    408 guys, i have an exhaust question. Obviously this is going to vary from one setup to the other, but in general would you guys say that a 408 stroker windsor has the "big block" note? In general, i would say that i can tell the difference between a loud small block and lets say a 440, 428...

    Water pump bolt size

    Can someone tell me the size a thread pitch of the far right side water pump bolt? Its the one with a stud on the end for locating the AC bracket. I snapped the original and the others are fine so I'm just goin to replace it with a hardware store piece.

    Cool paint idea

    Was just watching TRUCKS, or i guess its called truck tech now. Anyways, they painted a short wide chevy a real dark blue and then scuffed the hood and tailgate and painted flat clear super sport stripes. looked really cool IMO (not that its a new thing, seen it before). I was thinking it would...

    Pulling engine for H/C swap
