    "POSI-TRACTION questions??

    1994 GMC K1500 5.7 w/auto trans. We are in the process of fixing it up and haven't driven it much. It is supposed to have "Posi-traction" according to the option list. However, I happened to have the back end jacked up today, and when I turned one back wheel, the other one turned BACKWARDS...

    L98 into K1500--> HEADS?

    Hey guys. 1994 GMC K1500 w/5.7 I'm fixing up. Use will be everyday. Sometimes spirited driving, some weekend offroad, but nothing very intense. Just "hold my beer" fun. So I am going to replace the tired old 350 with a 1987 Corvette engine. I will freshen up the Vette engine first, though...

    Aftermarket trip computer for OBD1???

    Fixing up/restoring a 1994 GMC K1500. I absolutely love trip computers for monitoring fuel mileage and averages and other trip info. I know it was done and offered on OBD1 computer systems because my 1987 Vette has it. I have been searching and searching though, and cannot find a Trip...

    1994 GMC K1500 MUFFLER??

    Hey guys, I'm working on a 1994 GMC K1500 4x4 with the 5.7 engine. It's fully optioned out with ALL the heavy duty options fortunately. Eventually, it will get a fresh, warmed over engine with headers and true dual exhaust, but for now I'm just doing some much needed maintenance with a few...

    CHEAP Headers for 1994 K1500 4x4 pickup??

    Need really cheap set of full length headers for my 1994 GMC K1500 4x4 pickup. What changed that would affect fitment from between 1992 to 1995 on these trucks?? Some listings show fitment from 1988 all the way to 1995. Others show only up to 1992. Jegs has a set that would work perfect for...

    Hi guys, Thanks to the price of fuel, my plans/goals are changing... I am working on culminating my multi-year effort at owning a big block C4, and putting a nice 454 in my '87 Vette. Cool. Also, I am fixing up a 1994 GMC 4x4 pickup. That too was going to get a (very mild) 454, but with the...

    OFFROAD SETUP WISDOM??

    Hi all, I've been off-roading for approximately 55 years. One thing I've learned is that in virtually a matter of minutes, you can get farther away from civilization than you'd care to WALK back in case of a problem. Now that I am disabled with a bad back, making walking very far difficult...

    WIRING TPI FROM SCRATCH??

    I am seriously considering putting a 1987 Corvette TPI engine in my 1994 GMC 4wd pickup. I think it will make a great setup, and it's time, as the original engine has 300,000 miles. I will use the computer from the Corvette, and since I just will not pay Painless their inflated prices for a...

    BIG BLOCK HEADERS FOR '94 4x4??

    Hi all, I'm putting a big block in my 1994 GMC 4x4 pickup, and desperately need header options. I think I would like to go with intermediate length on this one, but will entertain all options. Due to the obvious nasty hassle of returning headers that don't fit, (plus the problem of not...
