advice: 500hp SB build

Moper,
now I dont feel like Im out in space, I have $10,000 budgeted for the 416. True I want to squeeze 600Hp out of it on pump gas,but I know I will be pushing the envelope.
I do want to take a moment to say the members of this site are a great bunch, and are not affraid to give you the benifit of their knowledge.
