I used car-part.com to find two engines recently for two friends who needed a replacement.No autocorrect.
www.car-part.com is a nationwide salvage yard parts search.
Very good resource. Just takes so searching not always easiest to find what you are looking for.
I'm in Ohio and one friend was in Florida. We found an excellent low mileage 4.6 for his Town Car 20 minutes from his house for $460.
