Do a google search for "rebuilt engine", check ebay, call around to your local junkyards. Prices will range from about $125 for a caveat emptor motor from a u-pull-it salvage yard to about $3000 for a professionally rebuilt, warrantied engine including installation.

Call any junkyards if they have any.If you want to look into a new engine,get a Jasper.Jasper has the best warranty and uses high quality parts.Jasper has a 36 month 76,000 mile nationwide warrenty and you can take to any place that is a Jasper dealer with no problems.
