$2000 is not alot of money to do a 440 the way theyre typically done nowadays. If you had a pre 1971 440 that runs good you could do the old fashioned rings gaskets bearings cam lifters and springs. Good carb and good factory intake or used aftermarket and some $140 headers. If you will be paying a shop to do the assemlby that will take a chunk of your 2k budget right there.
