I don't have results on the FAST 78 mm porting that matches your exact profile. However, I can tell you that a stock LS1 with the 78 mm FAST intake generally picks up 10 to 12 rwhp from porting. Porting your Shaner throttle body may pick up 1 or 2 additional, but the main advantage would be better throttle response. We would charge you the same special pricing for the FAST 78 as we've listed for the FAST 92.
