I was thinking about the fact its on the wrong side..
You could flip the head around and well then you have issues with length as your adding a whole new lot of timming crap on the other side..or if you could move the timing gear on the head itself to the other side.. can it be done?
Or just leave it mounted on the wrong side, ok it would be a compromise, you couldn't have narrow V angle and double up on some things in the intake which would get all snakey oneside , but seems more workable. Getting a mirror head made up of simular quality would be extremely expensive, time consuming and costly for a small operation. Unless ford could do it, which would be pretty simple to mirror the current CAM design..
I was thinking about firewall clearance. If I shortend the stroke down to 92 or 80 mm I would clear up a fair bit of space, has to be a much nicer fit than the massive V8 stroke and the rest.. 105.8mm at 90 deg, 92 or 80 mm with a 60 deg would be much more practical.. a inch lower each side with it being much more narrow.. Dam it its gotta be close, given that its a big engine and such a operation may allow to free up other space in the bonnet area with moving electrics, batteries, that a normal manufactuer wouldn't normally approve etc etc..
Im thinking 7.4L DOHC, 48 Valve, Twin turbo, Quad VCT, V12.. It would be a bit more rev happy, adjust limiter to 7500 rpm, new cams, oh yeh.. Avalible in special custom bodied 4 and 2 door varients based off the falcon platform..
