Your question needs more specifics..ie,,type of heads and induction. There are way too many variables to give a somewhat accurate answer.

i just to know what is the most power anyone has got out of a fully built all motor 408

here is how you measure that, go onto the internet and find out what the strongest 351 block you can find is and whatever that blocks max horsepower is you can probably max it out and maybego a bit furtherwith enough money.

CORR Pro 4 trucks make ~900 on ~400cid motors

nascar makes that much on 358's...

It's all in how you build the motor

I just helped a very prominent engine builder do a 420 SBC. Still 23* heads, cast single 4bbl. It made 945hp at 9200 RPM and 930hp at 9500 RPM. A few fellas have already said that your question needs more criteria to get an honest answer. Remember, we do NOT race dynos.......we race cars.
