    LSx Engine + T56 Magnum in a Roadster

    Now that my build is up and running, I wanted to create a thread to capture my journey of installing an LS3 stroker and any questions others may have in pursuing what I believe to be the best bang for the buck engine package available. I grew up in a family of Fords and drove/wrenched a '65GT and '88GT from HS through college. Many years after that, I found myself in a C5 Z06 that I modified with a supercharger + cam + alcohol injection. It was amongst that in which I purchased HP Tuners and learned how to wrench on and tune the LSx platform.

    Specifics of the build:

    Engine - BluePrint Engines 427 ci LS3 (package)
    ECU - GMPP E67 Connect & Cruise with DBW (package)
    Trans - T-56 Magnum (TUET11009) (package)
    Clutch - McLeod twin disk (package)
    Bellhousing - steel scatter shield (package)
    Shifter - Hanlon Motorsports midshift conversion
    Shift Lever - Hurst 5197 (ref. https://core-shifters.com/collection...oe-knob-thread)
    Headers - Gas-N custom 1-7/8" primaries bare SS (Georgie's Frankenstein jig made two trips between MA and TX)
    Engine Mounts - Dirty Dingo Mustang 1996-2004 LS Ford Upgrade Conversion Mounts (ref. https://www.dirtydingo.com/shop/prod...Cancelled=true)
    Oil Dipstick - flexible eBay LSx dipstick

    DBW go pedal installed with custom bracket:

    It fits:

    I ran -6AN PTFE lines for the PS and a regular -10AN for the reservoir back to the pump:

    I ran the GMPP bulkhead to the cockpit to capture:

    • Tach signal
    • Vehicle speed sensor (for cruise control)
    • Reverse lockout wire (activates solenoid to allow reverse at speeds <3 mph)
    • Throttle position signal to allow my WB 02 gauge to only light up during power enrichment scenarios
    • Ignition cut off wire for electrical disconnect
    • Check engine light on dash
