Re: RH drive F150 Harley Davidson !!
A mate of mine has one of these down in Port Melbourne. Very interesting under the bonnet! The back 1/2 of the engine is up under the firewall. (be a pig to work on?) SOHC 5.4 with roots type blower, mounted where a supercharger should be (in the valley) He has aftermarket fuel rails, bigger injectors, under drive pulleys, & coldair & reckons 550hp? It is a huge mother though, around 2600kg. And yes, I believe $115 odd big ones.
I'll get a pic or 2 next time I'm down there.
