I have a 2003 Mach 1 that just rolled 167000. It leaks oil, has a little tick or rattle and it starting to show it's age. My question is, where can I find a new 4 valve 4.6 long block or short block. Everywhere I look it's all coyote stuff. I understand the coyote is a great motor, and I'd love to do the swap, but money wise it's not really an option.
