Question about a 350 setup

I came across this engine. I am looking to buy it if it is something I can build a street-able motor out of it. The lifters have never been installed and the engine is never been run.
So if I change out the carb, intake, and cam to something more mild would this be a good setup. I am not sure what cam or carb/intake setup but I would like to stay in the 425-475hp range. (The guy told me with the set-up the way it is it would be right around 600hp) Any info would be greatly appreciated.

Here are the specs:
Bottom end :
68 4 bolt main block. ( .30 )
Steel Crank ( .10/.10 )
H-beam rods.
TRW forged 11:1 Pistons.
Fluidamper.
Pete Jackson gear drive ( Noisy ).
Herbert Roller cam ( 308 duration )
Roller lifters.
Rev kit.
Moroso 8qt. Pan and pickup.
Melling HV oil pump.
Polished "short" aluminum water pump.
ARP Main studs.
ARP rod bolts.
ARP Head studs.

Heads :
1965 Double Hump 350hp 327 vette heads.
Extensive porting.
Screw in studs.
Guide plates.
Manley valves ( 2.08/1.6 )
Manley push rods.
Crower roller rockers ( 1.5 )
Moroso rocker stud girdle.
Fabricated valve covers.

Intake:
Wiend polished tunnel ram.
Dual Predator 6000 carbs.
Scoop for carbs.
Dual feed line w/ psi gauge.

Also comes with a Unilite distributor w/bronze gear.
Low Alternator mount w/ Alternator.
Crankcase evac kit.
Full length headers.
All the gaskets needed to install heads, intake etc...
Nice front mount motor mount for drag application w/ isolator pads.

The 11:1 compression ratio is too high for practical on street pump gas use.

A milder cam with shorter duration will make matters worse and the cylinder pressure will be even higher.

Build your own motor with a pump gas compatable 10:1 cr. Max 10.5:1 for the street. 10.5:1 requires the best availble pump gas and a very good tune.

Much beyond this is beyond what is practical for daily street duty.
More pain than gain.

10:1 works great.

Run it and Have Fun!!!

That is the answer you want to hear!! You can run more than 11.1 on the street and have have fun with it. I don't think you would want to drive it to work everyday, but to thump around town a couple times a week and get a cheeseburg on saturday night at the local drive-in would be fun. Ditch the carbs and put a set of Holley 660's on it, make sure they are matched. I had a 66 chevelle set-up almost the same way 355 11.1, old school tunel ram with 660's, th350 4000 stall, 3.55 rearend gear, ran 11:80's through mufflers without nitrous. I did run race gas on the street, another alternative is +100 E85, the good stuff. If you don't mind working on it would be fun. If you want to set-it and forget it this is not you, this will be babysitting project!

I'm guessing this is a 350

personally i think i would steer clear anytime someone has a 350 with what sounds like a stock crank (turned .010), and says it makes 600hp. to make that much power out of a 350 it would have to have in the 12:1ish comrpession, be turning 7500rpm (which would not fair well for the I beam rods or steel crank). then they say that have that much money into parts but yet put a set of 50+yr old design heads on it, i dont care if they have extensive port work done, that only means that they have a huge cross-sectional area and have horrible velocity in the lower lifts which makes for bad volumetric efficancy and crappy low end. i would be suprised is this motor made 475-500hp
