Anyone Got A Combo Like This

The heads are as cast factory Performer RPM Edelbocks with Comp springs. I've been told by a few people that it would make 650 hp. The guys who built the thing the first go around (Barrett Racing Engines) were thinking that It would make around 700hp with ported & polished 452's milled .50 w/ 2.19 in 1.81 ex. I'm thinking, hoping that it will make 600hp with the Edelbrocks.
It may be a pipe dream, but I'd like to be able to get into 10.50 range.:dontknow:
