5.3 vs 5.7 Same mods, t70 turbo, 317 heads, ls1 cam, ls6 intake. Just different blocks. Lets say @ 10 psi, how much more power would the 5.7 put out?

I was asking because a local fbody with a t76 broke off a 11.1 this weekend @ 7 psi, with a 5.3 on street tires. Im trying to gauge what I should be expecting with a t70 @ 10psi on a 5.7 :p
