5.3's will make more due to the higher compression. how much more probably depends on the setup.

Thats about the jist of it. 5.3's carry a compression advantage over the 5.7 head due to the smaller chambers, but otherwise flow characteristics are nearly identical...The power increase will come from compression..

I noticed on Patriots webpage the 5.3's and 5.7's had the same flow numbers. Your post helped answer the question I was having.

Now I need to know if my G5X-2 cam and the 5.3's work well together?
