I have used the in-game text files to put a Supercharged modern V8 engine into the 60's Dodge Charger where the exhaust lines up etc. To add this into your game, simply locate the Dodge Charger file, add a text document named config1.txt and paste this into it:

Then ensure you also have a bodyconfig1.txt file and that both new files are in the original folder. re-start your game and you should be able to have this car. this engine is capable of 1500bhp in this setup with all of the tuning parts.
