From my short experience studying the 5.0 Mustangs it appears that a stroker 302 block is the best way to go. Even slipping in a 351 causes many minor changes which really pushes up the cost of the swap mostly if you want to run a EFI car with stock type accessories. The Cobra R was made from the factory with a 5.8 in limited run, and lots of conversion parts are around. Yes 460's can be made to fit, but expect to change lots of things and dont expect to pass emmissions etc.
