Manifold swap s550 and s197
Interesting topic.
I have not come across any info in this, but I wouldn't expect too much gain on a 11-14 Coyote. The S550 is a bit more powerful at 435hp and 400 lb/ft, but the S550 heads are supposedly higher flowing too. As in Boss flow rates. So my educated guess is that you'd also need better heads on our Coyotes to see the same power figures if you swap manifolds (and nothing else).
So I don't think cost/gain ratio is favorable on this mod. Just my somewhat educated guess.
What do you guys think?
