K car, anyone?
Since the later Daytonas were built on a modified (and only slightly) K chassis, most everything you'd want is a bolt-in. Find a wrecked Spirit R/T and rob the 224hp 2.2 Turbo/tranny/wiring harnesses/suspension/wheels,etc and you'd have a 13 second sleeper.
There's lots of info online about turbo swaps into non-turbo cars... check out

PS: Direct Connection used to sell a new front engine cradle to mount a small block V8 into the K body... now
that would be cool!
