Welcome to a milestone in automotive engineering! In this video, we showcase Larry Hofer’s first-ever 8.1-liter big block direct injection with variable valve timing C8 Corvette conversion. This monumental project, which took over two years to get to this point which demanded countless hours of re-engineering, manufacturing, and designing critical engine components and sensors to fit the massive 8.1-liter big block into the refined architecture of the C8 Corvette.
Unlike many Horsepower TV and reality shows, this video delves deep into the real-world challenges faced during the conversion. It’s a raw and honest depiction of the blood, sweat, tears, and critical thinking required to make this dream a reality. This is a complex conversion advanced level wrenching. This video features the entire process in chronological order, witnessing the complexity, difficulties and struggles Larry had to overcome to achieve such outstanding results.
Prepare to be inspired by the dedication and innovation behind this groundbreaking project. Watch the full journey unfold, from the initial planning stages to the triumphant startup and run of the world's first 8.1-liter big block C8 Corvette.

    Man this is a level of tenacity that is rare
  • @TheMrDarius
    That thing is going to be wild. Can’t believe I’m seeing a big block running direct injection. Pretty amazing.
  • @Chevy2856
    This the best thing I have ever seen in my 53 years of life, this way more than great!!!! 👍👍👍

    It’s time GM brings the big block corvette back.
  • @craigbowers4047
    I doubt anyone asked for or expected this build, but holy crap is it awesome. The effort just to source one off parts and make everything work with the OEM software is beyond impressive. Surely GM has to be blown away, too. It's a real shame the 8.1 never got the love it should have especially since the godzilla is being supported in the aftermarket. Continue on and I hope you'll be driving it soon.

    40 years old and I’ve become a fan boy to a fan boy of some of the baddest grandpas on earth. I can’t get enough of

    Larry just wanted to prove old guys can deal with modern technology computers and sensors. So he thought for a while what would be the most difficult swap take an old big block and convert it to run new technology in the most difficult car ever with it's massive amount of electrical connection and huge wiring harness there's no doubt soon it will run and perform just as he dreamed up one night
  • With two of you tenacious, super intelligent and capable guys working together you have such a team.
  • @chevydillan
    These people are absolutely genius. What an amazing accomplishment
  • I knew I recognized Larry's voice! He saved my c4 when my optispark went out. I never took my vette anywhere else. Im so glad to see hes working his magic on the new C8s. He is such a wealth of knowledge on Corvettes. Its nice to hear his voice again. Keep up the amazing work!
  • When a man just wants to drive his big block C8, this is what you get 👍🏻👍🏻
  • @THESLlCK
    This is the best project on youtube right now
  • @richardmeza5647
    For tuning support I'd recommend Peitz Performance in Tomball, Tx. No one knows these C8's like the team there
  • @bcbloc02
    You could have cam to crank timing physically perfect but with moving that reluctor wheel to trick the ignition timing the more you move it the more out of phase the computer will see even though it technically never changed the physical relationship.
  • @mikeh.753
    Damn Larry's a space shuttle engineer. This is unbelievable.
  • @jasonsapp792
    The level of performance this offers is going to be , hate to say it, game changing
  • @AxeRedrum
    What you have here is a Man challenging himself. Amazing stuff. Bravo 👏🇺🇲
  • Was waiting for someone to say, I think the reluctor wheel is 180 off…😜 Impressive effort and accomplishment.
