If all you have done is gone .040" over-size on the bore, used correct over-sized pistons and rings, resulting in the same compression-ratio, and are using the original cam, heads, intake, carb, etc., I doubt you'll see much, if-any, change in HP/TQ from it's original specs.

ALL that you have really done is make sure that the cylinder-walls are 'round', and that the chamber is 'sealed' via new rings:
those 'extra' 7" of displacement won't do THAT much for you.....

Agreeing with Glensgages ; at stock ratings of about .8 HP per cubic inch , you'll see about 6 hp and 3 ft/lbs .

norway:

which Edelbrock carb, which intake, what cc heads, which pistons producing what C.R., what exhaust, etc......
:confused
ALL of these little things matter greatly when making a 'guesstimate' (and that is ALL any of this really is here) for your 357" SBC.

If the motor is in-pieces (un-assembled), post any additional info (part #, sacting #, etc.) here, and maybe someone will offer-up a suggestion.

Sorry I can't be of more help.....

The best metode to determine how many hp you have, is to run the car on a dyno, then you don't have to guess. If you live in the southern part of Norway it's easy to find one.

norway,with those small valves you'll be lucky to see 300 h.p.
flow equals go, there's not much flow through those valves.mike
