* Engine bay space: While it *might* fit width-wise, the length and height of the 454 are significantly greater than the stock engine. You'll likely need significant modifications to the firewall, possibly even the inner fenders.
* Transmission: You'll need a transmission capable of handling the 454's torque, likely a heavy-duty automatic like a TH400 or a manual capable of the torque. The transmission tunnel may need modification to accommodate the larger transmission.
* Exhaust system: Fabricating a custom exhaust system will be necessary.
* Suspension: The extra weight of the 454 will put a lot of stress on the stock suspension. Upgraded suspension components are highly recommended, possibly including stronger springs, shocks, and possibly even a rear end upgrade.
* Wiring harness: The existing wiring harness won't be compatible. You'll need a custom wiring harness or extensive rewiring.
* Cooling system: The 454 will generate significantly more heat, requiring a larger radiator and possibly an upgraded cooling fan setup.
* Computer control: You'll need a suitable engine management system (likely a carburetor or aftermarket EFI system) to run the 454.
In short, while technically feasible, it's a major undertaking that requires significant mechanical expertise, fabrication skills, and a substantial budget. It's not a project for a novice.
