Where can I find a good F22A1 engine to use for upgrading? I'm looking for one that has decently low mileage or is at least well taken care of....

 

have you tried ebay, some of the salvage yards that sell parts you can email to and request if they have your engine. also on the internet google search there is a site that you can enter what you are looking for and the salvage yards will answer what they have and the amount for the item.
