You're a bold soul. But the fat block is going to take up some space. Get some chevy frame mounts (unless you already have them in there) and start with that. With a 454, your driveline will need to be beefed up as well. Or you could find out what to replace when you break stuff. 🙂 You've got a job ahead of you. Not horrible, but challenging. And putting hydraulics on it as well? That's a pretty good sized undertaking, but it can turn out to be a fun project. I'll fire up the popcorn machine. Welcome.
