Can a 360 internally balance if you use a light weight rod like a SCAT I beam and a piston that is a little lighter like a KB107 can it be internally balanced with no mallory?
I am not causing global warming, I am just trying to hold off a impending Ice Age!

I don't believe so, closest I have seen is a 360 I had that had 6.625" Aluminium rods with a ultra lightened flat top venolia piston with a thin wall wrist pin. Piston and pin weighed around 440-460 grams. Whomever balanced the assembly welded extra material to the ends of the counterweights. I don't see it happening with off the shelf parts, you would need atleast a couple slugs of mallory metal.

The 360 in the Dart is internally balanced. We used a stock cast crank, flat top SRP pistons and Scat I beams. I don't know the weights but I do know the machine shop had to drill some holes in the crank to balance it. No Mallory metal needed.

Could you post the balance sheet I'd like to see the weights of the components used in your build

Our 360/408 has Scat cast 4" crank, Scat I-beams & Icon flat tops (not light) and took one very small slug.
