    Putting a carburetor in a TBI based truck.

    My kid has a TBI to 4bbl adapter plate. New, never used. He swapped the whole engine in his 94 to a ZZ4 350 crate motor and used a Fi-tech throttle body system. Still using the 4L60E with the factory computer for shifting. All we had to do was tie in the Fi-tech TPS to the factory wiring and...

    Why are my Lo Beams burning out?

    I run the ZXE Goldstars in my 2012 GMC and every 10 months almost to the day, both of them will burn out within a week of each other. Sylvania says it is because they consider it a high performance bulb and that is what is expected. Luckily most of their higher priced bulbs do come with a 1...

    95 Chevrolet K1500 5.7 TBI to Carb Swap

    You will definitely need the TPS to make the 4L60E work. I helped my son install a Fi-Tech on a ZZ4 crate motor in his 94 GMC K2500 last year. Hi truck has the 4L80E still controlled by the factory computer. We just made a Y-Harness and tapped it into the existing factory TPS plug. We also...

    94 GMC K2500 with Fi-Tech EFI

    I think that was another option for my kid. I'll have to check his parts box, but I thought his replacement motor might have came with a vacuum distributor.

    94 GMC K2500 with Fi-Tech EFI

    This engine came with an upgraded Summit 850200 Computer Controlled Billet Distributor. To keep using this distributor I believe I can install the MSD 8861 HEI Bypass module which bypasses the computer control module and allows you to just use the magnetic trigger. Then I could use the Fi-tech...

    94 GMC K2500 with Fi-Tech EFI

    So my son bought his first vehicle, a 1994 GMC K2500 with 5.7 TBI. The engine is shot and he got a great deal on a lightly used 350 ZZ4 crate engine with Vortec heads. He's purchasing all kinds of parts for it inlcuding a Fi-Tech EFI, 30001. Of course this is his and my first build. We've...
