* Motor Mounts: You'll need motor mounts specifically designed for a big-block (454) in a '67 Chevy truck. Stock small-block mounts won't work.
* Exhaust System: A 454 is considerably larger than the stock engine, requiring a custom exhaust system.
* Steering: Depending on the specific 454 and its accessories, you might encounter clearance issues with the steering linkage.
* Transmission: The transmission and associated components will also need to be compatible with the 454. You might need to upgrade the transmission and/or driveshaft.
* Radiator: A larger radiator will probably be needed to handle the heat generated by the bigger engine.
* Wiring: The wiring harness may need modification or replacement to accommodate the 454's electrical system.
In short, while it's *possible*, it's not a straightforward swap and requires mechanical knowledge and potentially significant fabrication work. It's a popular swap, so plenty of information and parts are available, but it's not a beginner project.
