How much power from intake swap?

So, how much power are we going to gain/lose with this intake swap??

Going from a 383 Victor to Indy Tunnel ram.

Heads are MAX Wedge size ports. Victor port is .125" shorter. Tunnel Ram is Max wedge size. Single Dominator, nice CNC spacer and has a Hump welded in under carb pad to help air flow to all the runners from the central mounted carb.

So what do you think???? It made 730HP last time with the Victor and the 1050.
