    1990 350 TBI - Fitech Swap

    Hi, I recently built a 350 vortec with fitech injection and HEI ignition for my 1990 k1500. The motor runs fine and everything works good, except one small issue. When i turn on my headlights, the ignition comes on. I think there might be a ground wire from the old TBI computer that's missing...

    Choose Cam for forced induction 350

    Im planning to run this with port injection, have access to a machine shop so i will probably modify the TBI intake or just build a new intake from scratch. Just to experiment, i have some injectors and sensors laying around

    Choose Cam for forced induction 350

    Hi Guys, I recently swapped my TBI for a built 350 with vortec heads, new cam, injection etc. My old motor is just laying around, i'm thinking of doing a really cheap turbo setup and putting it in maybe a tractor or something. I can get a cummins diesel for free, injection and ECU is really...

    700r4. Did i mess up?

    Should it be placed in front of the plastic washer with two dots on? Between the pump and the plastic washer

    700r4. Did i mess up?

    I have no idea where it came from, i looked at images and the only similar rings i can find in the transmission are inside the pump. Could it be on the shaft from the converter to the pump?

    Hi! I haf the front pump of my 700r4 taken out, when I reinstalled it, I forgot to install a big washer on the rear of the pump. Is it okay to go without or do I need to install it? Thanks

    TBI/Vortec Swap. Will accessories fit?

    Hi, I'm currently working on my first project, the motor is done in a week or two and it's soon time to lift out the old motor. It's a 1990 350 Tbi with 700r4, the new motor is from a 96 Chevy Express. My question is, will the flexplate, starter, power steering, all all other accessories fit my...

    FiTech EFI for 350 TBI/Vortec

    Thanks for the input, unfortunately i didn't see all your post before i ordered the 400hp Fitech, it should be a mild engine and the reason i went with fitech instead of GM TBI was the issues with finding the right parts and knowledge about flashing, burning chips and modifying ECMs in Sweden. I...

    FiTech EFI for 350 TBI/Vortec

    I'm looking into the cheap Fitech 400hp for 795USD, it can not be used to control timing. Looks like i'm going with a HEI with mechanical and vacuum advance since the old distributor has 150k miles on it and i will have to swap out the distributer gear anyway. But, i will still need to control...

    FiTech EFI for 350 TBI/Vortec

    Okey, i basically have two options, I am trying to find pros and cons with the two different setups; GM TBI with Dynamic EFI (430USD) + Computer controlled distributor (180USD) + Heated O2 (80USD) = 690 USD (897 USD with taxes) +Cheaper +No need for making new linkage for transmission +Computer...

    FiTech EFI for 350 TBI/Vortec

    Hi, i'm currently building a new engine for my 1990 K1500. I bough a L31 Vortec Longblock and i was planning to use the TBI from my old motor when i found the Fitech EFI 400hp Throttle body injection. The problem is that the Fitech is unable to control timing, do you guys know if it is possible...
