I didn't see anything about the direct swap of a N/A 99-01 5.4l modular motor swap into a MN12 thunderbird chassis when I clicked search about... 10 minutes ago, so if I'm wrong...I'm sorry, but here is my little thread I'd like to go into technical discussion about the swap. -BTW this is about a 2v motor, not the 4v or the 4v SC cobra/lightning motor -
Alright, so I'm looking at a 1997 thunderbird with a 4.6 in it for a good price, but then there is the yearn for more power just like any other car, so what better to start going with than more displacement????
the 99-01 5.4 comes with the PI heads/cams/intake manifolds and everything else that you would normally do to your 4.6... but it's already there and ready to go, not to mention the added power that comes from more displacement.
now, physically the two motors aren't that much different, the 5.4 is wider and the deck height is a little bit taller (less than 2in).
So if that is the case, honestly the swap wouldn't be too intricate and or invasive to swap out the two motors. Worst case scenario the intake manifold wouldn't fit correctly and that would be rectified either with a cowl induction hood or with adapter plates to put the 4.6 PI intake manifold on there. dimensionally the two are close and it doesn't look like too much fabrication/relocation and or modifications would be necessary for the motor to fit into the engine bay of the thunderbird.
so, what do you all think about the swap? lets get some ideas flowing and see what technical resources pop up.
