This seems very doable on a 555 Pontiac with 350 cfm e-heads.
What do you guys think?

there's quite a few guys who made that much HP with a Pontiac in the past 45 years....you can make 675-700 on the stock block, with a 3" main, and a cast 455 4.21" stroke crank, with those heads. but you'll need a tunnel ram and 2-4's, or a big aszed Dominator.
i.e. 2-660's or 2-750's or ? a 1350 Dominator
