$3 to 5k will build you about any 240, 383 or 440 engine, you should be able to do a 440 for $4k. And since bigblocks are the rage why not.........now you can buy a shortblock or probably even long block 340 or 360 for a little less.........ebaymotors also has some good engines or components that come on worth the money cause other peoples priority changes
