The FE you see here:

with alum intake, heads (19 lb each), alternator, water pump and heavy steel canton 7 qt pan, thick FPP shaft mounted roller rockers, etc. weighs just over 500 lb (503 to be exact). I don't think you can build a 351 anywhere near 250 lb.
Although I have never put one on the scales, I would expect a 351W with cast iron block and aluminum for intake, heads, water pump and the like to weigh over 400 lb. This equates to roughly a 100 lb difference.
The 351 is certainly a great motor and can be a cost effective (hp per dollar) solution.
The
lowest HP version of the 427 ever produced for a car was rated at 410 HP.
