.. that doesn't make sense. soft brakes are caused by air (or moisture) in the fluid, nothing to do with the booster.
Poor vac to the booster makes the pedal hard to push (and your cam won't cause that. I run a 108LSA cam in the race car and vac is ok)

I would be looking over your braking system and checking out....

As said above, my bet would be air in the system (or something more serious).

109LSA shouldn't cause the issues you are having.

Its not major. The pedal is harder. It just isnt pulling up like it was before the motor swap.
Ill change all the pads and bleed and see how it is then
