Who ever wired up that manifold needs a pat on the back.
The trumpets look a little short,

Phil I did the wiring,
tried to hide as much as possible,now running Autronic SM4 comes with a nice flying lead harness..
Yes trumpets are thew shorter of the two DC&O make 65mm I think,would prefer the 100s but would put them too close to the bonnet for the filters ,at the moment just running socks,yet to do cold air...

Are the axles going to last?

Hopefully Yes Ben 31 spline Mosers doing the job...

There is more to this than just changing heads and cam and expecting everything will work just like it did when it was stock.

Good info on the workings of the EEC but not entirely correct for the earlier generation Ecus,
Their not that bad and I was running an EEC4 ecu making 280ish rwhp,
I programmed a chip for it using a J3 (diagnostic port) adaptor which is like a piggyback chip.
It had great manners and I only had to concentrate on timing,injector size and a few other things to get the most out of it,
Proven on the dyno would pull a perfectly flat 13-1 af ratio at wot..
Im pretty sure Nc fairlanes are EEC4 and maybe a few late ones were early smartlock ,both very adaptive to mods.
Ashley Bright is also running a ED smartlock ecu with H,C,I mods without problems and also making good power and no chip at all...for now anyways.....
The wide open throttle table isnt fixed for fuel,
it just specifies a target AF based on load and rpm.
Make it a more efficent airpump with modifications,MAf measures the increased airflow and converts this to load,the tables have plenty of resolution for this...
Long term fuel trims can also be reset and adaptive control can also be disabled,simply pulling the fuse on the ecu before Dyno etc gets it back to the base trim.
But yes by the time ford got to Au and EEC5 they had made the things too complex and can be tempramental,similar to the 95 american mustang ECUs
Their Is a lot to this and dont want to write an essay,
Just my 2 cents worth...
I would not be concerned too much about your ecu Pete,
It will do the job.
Leave the chip till last after mods not before on a stock engine...
You would probably make as much gain by bumping the base timing on yours to 14 or so over the stock 10,makes a difference...
The factory timing curves are pretty soft...
Theirs plenty of 10 second mustangs around with EEC brains..

if we can get you, Phil and I to drag down the straight, the induction howl should be amazing

24 throttlebodys and about 1200 or so horsepower,
now that would be awesome....might actually create a vacuum....
