Building a 454?
Nothing about upgrading it is cheap and I doubt it is worth your investment IMO

He is building a high end stroker 8.1. You might want to check out his channel for some info. I believe he is also using parts for Raylar.
Hey. Here’s a neat read about the 454 in the 2000 model 3500 series of engines. The 8.1 is around 496 cubic inches. You need to verify what you really have. If it’s the 7.4L (454), your good to go. Build away. Richard Holdner on YouTube has many videos about building these engines and some of them do end up at 1000hp. If you have the 8.1, sell it and get the 454. Huge difference in parts availability. Here is a picture of my 454 build that is now a 496 cid all forged heavy breather. I hope this helps. Good luck.
