Adding 22 cubes,,, power increase? 528 to 550

thanks in advance! Ignition is a new MSDdigital 7. Plugs at .025 but i can try .022 after a few passes. I wanted to dyno this deal but the piston coatings dictate a very long three time full warmup cycles with total cool down between each cycle. Timing will start at 33 since it ran best at 34 before.

So do a long 3 time warmup on the dyno.

In my experience increasing cubic inch via increasing stroke has a far more pronounced increase and effect on power vs. increasing bore size.
