This guy blew his 4.6 about two months ago in his '99 Cobra. Here's the vid:
So he went with the 5.4 block:
5.4 Block bored/index-honed .020 with deckplates, Align honed, decked square
Forged 5.4 Crank
ARP main studs
Manley/Primeone rods with ARP 2000 bolts
Ross 10cc pistons
9.25:1 Compression
Ross plasma-moly file fit rings
clevite 77 trimetal race bearings
Fully Balanced rotating assembly
Billet Oil Pump Gears
Canton 7qt Road Race Oil Pan
03 Cobra Heads/Cams








Pretty sweet!
