pezzonovante88,
I think the short answer is "yes, you could make near 650hp with a 482 ci FE with a set of 48s (As Chas said, bigger would be better)
But....It would be a poor street motor: peaky, angry, temperamental and a generally grumpy bastard!
In the end I think you would be wishing you had spent the large pile of dollars it took to build such a beast, differently.
I wont deny that Webers look great and that keeps the "Mystique" alive. But as I have said before, they are much better on a garage shelf than in a running motor.
Individual Runner EFI is a better option if you want "The Look" and you want it to run like it should.
