At the less than 550 HP level a stock 4-bolt main 350 block will be plenty strong enough, even a stock 2-bolt 350 block will be fine at 400 need for an aftermarket block.

454 is nice, big cubes make big power easier, but might open up a cooling nightmare in the narrow '41 nose, require an expensive radiator and expensive custom headers. Big block performance parts are also more expensive than small block.
