Well, Ford has basically said there wasn't going to be a V8 territory. And it looks like they're right. As hinted by GP the V8 won't allow fitment of all ancillaries along with the 4WD drivetrain.
When you look at a V8 equipped BA you can see what they mean - the engine is very wide and with the heads and block interface, exhaust etc the amount of room alongside the engine is next to zero.
Well, from my previous work life I have a contact who is involved in shipping cars of sometimes sensitive nature. He tipped me off and lo and behold a car comes through the cargo shipping area in a wooden box (sitting on a steel cradle) for freighting to Dearborn. Access was cramped but I tell you this vehicle had a group of five header pipes on the LEFT of the vehicle visible on the underside (hard to see due to the steel cradle and the tie down straps). Also, the sump well was almost at the very front of the car suggesting a very long engine (the driveshafts ran BEHIND the sump).
Unfortunately like I said access was very hard and light very poor. But it makes me wonder - what links up five and a very long engine?
I reckon for packaging this has to be a V10. No doubts. Thinking about it the V10 is a narrower engine and length isn't an issue because the six fits. Plus it has the torque and ability to pull long gearing that may provide the market necessities of torque and economy????
Holy schmoly - maybe this is the link from those 'Barras' that some people swear they saw wioth V10s.
JR and Sparkles may have to eat humble pie if this all adds up!
