Pivoting from 340 to 360

Thanks for the input. I'll run the idea of flat top pistons by the MMM (Master Mopar Mechanic). But I already have the stall converter in-place.
You have a Master Mopar Mechanic at your disposal and you are going to throw all these other cats into the bag? Going to be a bunch of scratching and clawing. And the poor MMM is going to have to sort through all these other conflicting ideas with you? Just let the MMM do his job or he's no MMM. Why even have the MMM if he cannot figure out this stuff?
