give us a clue (bhp rating)

[saabster]

hi boys and girls. any ideas as to what bhp i will be getting from my 5.7lGM V8
as i have uprated the cylinder heads with large valves 3stage angle job+ported and polished,flat top pistons (comp.from150psi-195psi),high lift cam+eagle crank.A ROUGH ESTIMATE WOULD BE GREAT.CHEERS SAABSTER

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

i know bi wouldnt get an exact figure,the engine was 260hp standard.so i was guessing it would now be around 330hp?the heads alone was supposed to add 40hp.so i was just trying to get someone elses rough guess.thanks for the reply (redtech)anyway.cheers
