Dana flow tourque vs. Lightning headers
I am looking at purchasing either the Dana flow tourque manifolds or lightning headers (freshwater). Boat is run in freshwater only. I have seen the results of the full throttle marine dyno reports and was originally leaning towards the lightnings. But after seeing the report by Full throttle marine I turned my direction towards the Danas. Both options are around the same cost. Hoping someone can provide me some info on their experience that they have had with either product? Boat they are going on is a 2002 Nordic Rage 25 with a 496 HO and a bravo x drive. Boat has a whipple stage 2 ECM upgrade.

How do you like the Whipple stage 2 upgrade? I'm going to do the same but was going to use the Diamond Performance Thunder & Lightning cast aluminum headers and a labbed 28 4 blade prop.

I like the Whipple stage 2 it definitely helped the midrange and got me to top end a lot quicker. You will need to run 91 oct with this programming. When sending your ecm out make sure you indicate that you plan on installing headers as this may change the way they program it for you.

I have a 2008 Heat with a 496 HO and Danas. They are great for the cost! and I definitely feel the difference in performance from the stock manifolds. I had to change props from a 24p to a 26p to accommodate for the increase in HP. I am very happy with them. My only issue what the wait time from Dana. It took almost 6 months to get them so if you go that path be prepared to be patient and call them for progress reports weekly.

What did you pick up on the top end? I have been talking with Bob at Marine Industries West and it sounds as though he has purchased the patents from Dana, Bob has indicated 2-3 week lead time, did you purchase your set when it was still owned by Dana?

I'm looking at building a 496HO with forged internals and installing the Whipple 2.3 on it and the Dana's as well. Can you tell me what you did to your motor when you installed the Whipple? Thanks!

The stage 2 that I had completed by Whipple was an ECM upgrade. You are on the right track though with the forged pistons. I recommend calling Whipple and talking to Dustin he would be your best resource.
