You should be able to get a remanufactured long block for far less than that. Pay someone to put in in & you may be up there.

Here are the links to my engine search in order from cheapest to most expensive.

For much cheaper you can also locate low mileage used, but for the effort of replacement I would go with a reman longblock. My .02
