One problem you may run into. If you put a V-8 in a 4 cyl mustang. Then have an accident and your insurance company has your car as a 4 cyl. Then when they investigate the accident and appraise the damage, they can denie coverage because of fraud.

Just a thought.....

5.0 fits the best, but most everything has to be changed over to a V-8 car. Brakes, suspension, EEC harness, etc
