    350cid small block chevy been around for a long time making from 165hp to over 800hp depending on pistons, crankshaft, size of valves, intake manifolds, exhaust manifolds, cam lift, rockers, rings, carburation, injection, t-stats and the list go's on to 350cid/5.7L engine any set of heads and flat top piston is just not enough information then to add that you're looking for brake horsepower (that is the power to the prop after the engine and transmission have sucked up as much as possible ) you can't get a good reply
    more information please
    sorry about being harsh
