I think you should call prosystems and post back here what they recommend.

A 750 seems to be the carb of choice for a 5.7/6.0 with moderate upgrades. Not sure what would be best for the lower output of the stock 5.3.

I would not mix a spread bore carb with a square bore manifold, if that is what your dual plane is.
