346 with stock 317s -- whats the average HP level?

What are you turbo guys making with stock 317 heads? Is it within reality for me to attempt to make over 700rwhp with a 346 and stock 317s? My setup is forged 346 (flat tops)
stock 317 (patriot springs)
Twin precision 6265's
6-speed

Thanks for the input!
Frank

Wow! our specs are verrrry similar! That's great to see that your making that much power with your setup! The only real difference I see between our setups are I'm running 62mm turbo's and Edelbrock Proflo intake. Congrats on the great #s!
