you're right, anything is possible. and, yes, after a good rebuild and several custom pieces (cam, rods, pistons, head studs, intake, exhaust manifold, head mods, etc) i'm sure it will do great.
if you're set on this route and willing to spend the thousands - sweet!! honestly, i'd love to see it!!!
now, not all those things will be required to make 285hp (or any of them?), but you should understand that lowering compression w/out readily available parts to swap in is no small feat. and if you go that far (plus a custom cam), you might as well go all out.
285hp LDT or dt466 - either way, i'm staying tuned...
