This manifold will only make more power on a motor that demands it. A stock block qr on a small cam this manifold won’t make more power. Maybe 2-3 hp more. But on a built block with aggressive cams at 8500 Rpm this manifold will really do wonders
That’s a nice compression lol. Some1 needs to make a more aggressive cam then RZ. It’s our most aggressive cam but it’s still smaller then any k series street cam lol
