There is a pretty big diff in runner volume on the eddy vs the China deal air gaps -- I measured it on a SBC one time --can't remember but is was a lot--guessing that the Mopar version is similar--the runner cross sections and overall volume was lots smaller on the china job--I can't see how you would be giving up much Tq with the eddy--it would be my choice
If you have both maybe tape them up and CC--hey bet you can see the diff with a tea pitcher and won't need a burret LOL
Thinking small carb may be helpful vs. a 750
