You have to decide whether you want a high hp engine that doesn't rev past 6500rpm or a moderately high hp engine that can rev it's ringer out.
Durability I say stroker. Stroker will make bucket loads more hp and torque @ the same rpm ie 6000-6500rpm. Lower rpm = less wear and tear.
In regards to durability of a stock stroke motor. I aren't saying it's not reliable. It just rev's A LOT
! Why rev it if you don't have to?
Let your wallet decide. If you can't afford a stroker? Go alloys and stock stroke. If you can? Go the 408 with the alloys
I always let my wallet decide what I am doing. It helps having all those dustmites assisting me with decisions
