What would it cost and take to put a 460 into an xf sedan? What could I expect the power to be keeping with in the emission laws when running unleaded and an efi system? Am I only dreaming, I hope not. What sort of cost and what would be the best gearbox be to handle the power?

dont think you could do it to an xf cause thay never came v8 powerd and its a pain to even get it engeneared for a 302 or 351

For a gearbox-can't go past a Toploader or Tremec 5 speed if manual. If auto, go an AOD 4-speed, C4 or C6.

Find a local engineer and ask them the engineering cost estimate, you may find the cost of that or effort will stop your plan.

But if you did, you can become SUPER FREAK !

if u were to fit a late model 460 out of a post 86 truck with the efi and bodgy cam/heads you can legally run it on petrol, best bet is to run an early d block with either c8ve/c9ve/dove heads or if you want to save a little on initial cost get a d series block running d3ve heads.

Just be carful that any 460 you buy doesnt have the very rare and very useless d2ve heads.

the first 3 heads mentioned will give you heaps of power with a mild hydralic cam and edelborck performer manifold for example without porting.

The d3ve even though bad on the exhaust side in stock trim can be taken out to provide 320cfm on the intake and 210cfm on the exhaust but be careful as most engine shops dont know how to port 460 heads properly and will grind right through into the water passage below the exhaust port floors when trying to achieve these figures.

that basically mean that on a resonable solid cam you can crack 550-590hp and more importantly 550 pounds of tourqe with around 400 pounds being made my 2500 rpm.

either way if you want head work or cam change u will be forced to lpg it for compliance.

as far as engineeringis concerned dependant on state regulations of course you should be able to pass as an xf has a very very similar front end as the xw-xd range so brakes springs etc should all be acceptable as there is only a 50-60 kg weight in crease over a cleveland. if you use a cast iron intake manifold it will be around 75kg heavier than a clevo.

It has been done legally but will cost you for the reports.
