'60s 427 FE 425 Hp side oiler......mpg?

Before everybody shoots me down, saying don't fit a BB to save money on fuel, I was just wondered highway cruising at 70, running at 10:1 comp, what miles per gallon would be the norm and also average around town?
Anybody actually tested this. Just wondering how in real life it compares to a modern 347 that seems to average 10 -15 mpg.
Also I heard with alloy heads and water pump, weight comes down to 520Lbs. Is that about right?
If there are any real life answers that would be really helpful.
