Will this fit my '99 F150's 2v 4.6? Assuming the GTs and F150s shared the same 4.6.
It's possible that it will fit, but uncertain. The F-150 version of the 4.6 featured a cast iron block and a few other differences, while the Mustang has an aluminum block. So, it's possible, but not certain, and we haven't tested it to be sure.
