I'm looking to use large displacement in order to avoid power adders. Info is seems to be limited.

Hi Frankie, generally for NA street build displacement is your friend. However at some point, the options that give you displacement starts to take away horsepower itself. Example a 4.5 inch stroke in a factory block Pontiac.
The length of the intake tract will find a sweet spot for CID and RPM range also.
