A else being equal, a bigger engine makes more power. If you are asking about the structural integrity of the castings, the 350 is a better block.
350 hp 400 tq hp means nothing it is just what the engine is rated at. torque is the actual measure of power
Yes. They are identical because externally the 350 and 400 are also identical.
About 400 lbs.
Most likely a 350 cubic inch or 400 cubic inch engine
typically 350 parts are more common and cheaper than the 400 parts.
350, to 400 lbs.
I would depend on if you are asking a Chevy man or a Mopar man. Personally I like the Chevy 350. If you are referring to a Chevy 383 made from a 350 block with a 400 crank, it would always make more torque than a 350. So if torque is what you're after, "there's no replacement for displacement".
no
YES a Whole lot better.
