I am tying to post that only and wont allow it

jeez

they have goodwins dyno test posted but not with headers, Using the newest Hardin Marine Manifolds and riser combo. 529 hp on the dyno. I want to see with the headers numbers. I have heard people claim 545 and even past that number for a stock 525 hp. I want to see that. I have never seen anything past 545 or maybe it was 542 something like that..

The engine lost 20 hp with the manifolds. I've talked with them at length about the manifolds so that I knew what to expect should I ever use them. The one thing that they do have going for them is that they are half the price of headers and you can get your existing tailpipes.
