if i up the comp , how much power will i make?
 

I have a 572 bbc 9.7-1 comp engine that runs on pump gas. How much power increase will i see, if i raise it to 11.5-1 and run av gas? It has dart 345 pro one heads, and .704 lift solid roller and 268-274 duration @ .050 and 114 lobe center. It is in a boat. Has dominator 8896 carb on it. Also would a 9375 dominator be a better choice for this application.? It dynoed at 720 hp at 6000 rpm at 9.7-1 comp. Torque was around 715 lbs.

just curious how do you plan to raise compression in your motor ?
