One of our fellow FFR builders had some difficulties with his donor 4.6l due to the FFR supplied
oil pans (which have now been corrected with the dedicated vendors and forum members redesign) and just ditched his donor engine. He replaced it with a BMW V12 with dual turbo's.
With the help of several very experienced builders and technicians they've created (re-created) one amazing vehicle.
I hope John doesn't mind me spreading the good word.
