Factors to consider:
* Application: Street car, race car, truck, boat?
* Power goals: What horsepower and torque are you aiming for?
* Budget: How much can you spend on the engine itself, plus modifications?
* Availability: What parts are readily available in your area?
* Maintenance: Are you comfortable working on the engine yourself, or will you need professional help?
