2.3 whipple vs 2.9 whipple

[2quicksvt]

I currently have a gen II 2.3l whipple on pump gas making 608hp 550tq on 17pds. How much more power would I get if I sold this 2.3 an bought a 2.9? Can someone give me some numbers on what I could expect on pump gas. With the 2.3 on torco it makes 663hp on 22pds. Would like to have those numbers on pump gas. Idk if there is a thread like this so bare with me. Thanks

Mine made 622 HP on 91 Octane and 686 on 110 Octane. That is on stock headers.
