    Air in my fuel lines?!?!

    I noticed bubbles inside my fuel filter after shutting off the engine today. Not just a few bubbles, it kept bubbling for about 3 to 5 minutes. This is after driving it for the first time in about a year and it sat for several years before that. The back story is that this square was bought with...

    th350 vent tube/check valve location and access.

    Ok, so I posted about foamy transmission fluid and got a few replies about the vent tube possibly being plugged. My new question is.... Can I access it without having to drop the tranny down? My square is lifted 6" and I can pretty much sit under it while working on it. I'm getting ready to go...

    Hello, I'm going from 37X12.50R16.5 to 35x12.50R17. The rims that I bought have a 4 and 1/4 inch back spacing so I'm just wondering if anyone has used this size.

    Stock jet size on a quadrajet for my 454

    I'm trying to get my Suburban to pass smog (California). I got said Suburban from my uncle who used to build race cars but passed away. I'm almost positive that he re jetted the Rochester in it for towing. It's a 77 3/4 ton truck with a stock 454. It was deemed a "gross polluter" by the smog...

    Foamy Tranny Fluid!!!!

    Just changed the tranny fluid and filter and fired up the beast and it started to foam from the mouth! Actually it foamed from the tranny dipstick but I must have lost at least a quart or two of fluid. It didn't happen right away, maybe about 5 to 7 minutes after I started it. I looked up...

    Kickdown Cable Bracket

    I have a TH350 and when I bought the truck the kickdown cable was not hooked up and it was lying between the engine and the passenger side fender. Seeing that it looked like the accelerator cable I moved it to the other side of the engine and bolted it to the bottom of the accelerator butterfly...

    Rockwell 2 1/2 ton axles anyone?

    I wanted to know if anyone has used these, how they worked out, and how hard they are to get? I'm just thinking ahead to possible upgrades for later. I plan on using my square for competition some day. I am still just trying to get it road worthy for now with some occasional 4 wheeling. Just...

    How many leafs do I have to add

    If I want to keep my 6" lift but get rid of the blocks in the rear, do I have to get all new springs or can they be added? I want to get away from the blocks. Also I may add anti wrap bars.

    Disc brake conversion doesn't have E brake

    I bought my truck with the disc conversion already done and that's great and everything but it doesn't have an e brake set up. I've heard that you have to use Cadillac calipers if you want a working e brake. Are there any other sollutions to this problem?

    Getting ready to install dual Skyjacker front shock kit

    Has anyone installed dual front shocks? I have a 75 GMC that has a 6" lift and has been converted to 3/4 ton axles. I'm for sure going to have to weld shock mounts on my Dana 44 because the previous owner cut the old ones off. I'm pretty sure that I'll have to move my break lines to drill holes...

    New from Santa Cruz CA 75 GMC K25

    GM Square body is AWESOME! I wanted a lifted truck since I can remember and was lucky enough to finally get one. It was someone else's project that couldn't keep it. My wife, who was still my fiance at the time, saw it on her way home from work and decided that I should have it. It had already...
