A passing comment from a pilgrim that admits to having zero experience with small block Ford strokers: reliability of a given engine is far more dependant on the quality of the machining, assembly, and components than the particular displacement. I have to seriously question why a 331 would be more reliable than a 347, other factors being equal.
There's a local Mustang drag racer who has made over 1200 RWHP with a turbo 347 without "reliability" issues.
