540 BBC build

So i have officially decided to abandon my 500hp 327 screamer deal, and go strait to real business. I would like to get some feedback on the build plan i have for a 540bbc.

Dart big M, 9.8" deck, either 4.5 or 4.6" bore
Brodix bb-2x (340cc intake) or bb-2xtra (365cc intake)
They come assemble with either 1.550 or 1.625 dual springs for roller cams
lunati 4340 sledgehammer 4.25 stroke, 2 piece rear seal
eagle esp h-beams with l-19 rod bolts (6.385")
Not sure of pistons yet
will have arp studs and fasteners throughout
a pretty agressive solid roller, in the 250+ range @.050
lunati voodoo 60233 (249/255@.050, .663,.680)
comp cam XR292R (254/260 @.050,.66,.666)
something bigger?
a victor or team-g type intake
hooker super comp's 1-7/8" x30" (engine swap header)


i would like 700hp+ N/A on pump gas, but i am not looking t squeeze every last hp out of it. i want a quality, thought out build. I have no problem checking springs every 6 months or whatever, i LOVE to work on engines so i have no problem pulling the motor every 6 months or a year to freshen things up.

this will be my daily driver, but i am looking for 10's in the 1/4 ( i have a bet with my dad, grandpa, and brother that i can do it, or else i loose $40 )

I am looking to make this a horsepower build, not a torque monster. i understand that i will be a little rough around the edges, but i can handle much more in a DD than most.

What i have to work with:
car is a 1988 camaro, not tubed or anyting, all stock.
i just got a new TKO 600 5-speed, and.... hate to say... but a 7.5" 10-bolt rear. i do have all aftermarket axles, eaton trutrac posi, and 4.10:1 gears.
the car weighs in at 3200# from the factory, but i stripped it and i will run it with no a/c, no heater, and only the basic need to be legal on the street and on the track. electric WP, alternator, and i might end up keeping p/s so that i can do a hydroboost brake system (for that sake of valve cover to booster clearance)

I need some advise on a few things:
Pistons, i need some kind of dome to get about 11:1 CR, and would like to be able to handle 7000ish rpm. I don't think i need top dollar Diamond or custom pistons, be something like Wiseco, JE, SRP, Mahle?
intake? do i need a dominator?
would a small single plane like a victor jr work, or a 4500 super victor?
how about those brodix heads? overkill? not enough velocity?
i have read into some other 500+ bbc build, and they all seam to use HUGE cams and less than 11:1 cr. when you get into really big cubes, is it easier to run a radical with being to insane?
are 1-7/8 headers big enough? 3" dual exhaust big enough? my only dilemma is my car. headers on a sbc in my car are a pain, and the stock exhaust was a 2-1/2 y-pipe!

even though it is my DD, it won't see too many miles. 20 miles to and from work 4 times a week, 40 miles to and from school 2 times a week. I will eventually be living on-campus after i finish my AS degree, so then it will be my show-off car. but anyways....

I won't have this built for at least 6 months. I Would like to have a solid plan so that i can buy parts along the way so i can find deals on parts.

i.e. i found those $570 esp rods for $450 new on ebay, i found a new $1000 holley ultra dominator on ebay for around $500. i would like to jump on these deals so that i can save a little in the long run.

advice, comments, and warnings welcome!
