Either can make the same power. But you will need to spin the 350 a little faster to do so.
The air flow of the cylinder heads is what determines how much power you can make.
Give brodix or dart a call and explain what you are trying to do.
If your starting from scratch I would consider a dart block or bow tie block with a 4.125 or larger bore. As the larger bore unshrouds the valves some what which also helps air flow/power.
It's also pretty easy. To build these blocks to 400+ CID
Hope this helps
