No they won't bolt on. They would on a 4.6 block though, and MMR has a great selection of those as well. Sorry I couldn't be more help.
Hmm, well if I were you I would call them and ask. I know your heads won't work on a 5.4 block from say an f150 or expedition, so I just figured it would be the same. I'd call them if I were youI found this after asking this question last night and believe it may disagree, unless I misunderstand.
All MMR shortblocks are available in either a 281ci/ 302ci/325 (4.6)or 330ci/358 (5.4) configuration and are compatible with all SOHC, 3v and DOHC cylinder heads.
The best thing to do would be call whipple and tell them your set up and ask what they have or recommend, might piece you together a pretty badass kit.I just thought about this, but what kind of whipple would I need to go on this? Or would that require more fabrication?
