Default Recipe for 800+ Motor

I'm thinking of building some motors for my 34 DCB over the winter and need some ideas of what direction to go. I want something that is going to be reliable and easy to drive around the docks. I want 800 horsepower. I am leaning towards Whipple system on a Dart or Merlin platform. Obviously I want to spend the least amount possible, but I am most interested in doing it right. Anyone done something like this before or have any ideas for me? Eric

I had 800hp Teagues/XR Drives in my 34 DCB a few years back, plan on investing in some spare drives I popped my first drive after 15hrs @ 120mph,,,not good,the 3rd owner of my boat did a Konrad drive upgrade shortly after he bought it

I know the drives will be a problem. Thinking of the Konrad solution. I have spoken with them already.

I would go with a nice 598CI, na with some good CNC heads. This will be the cheapest and a very reliable package with good idle quality. Then if you want to upgrade later, all you have to do is feshen them with lower boost and add blower. Then you'll be at 1000+hp. Also alot of people can build the 800 package.

I agree. You can make 800HP with some cnc heads and a hydraulic roller cam. I've seen it done 801 HP @5900. about 760 @ 5500

The N/A package would fit the bill and be less expensive. Tell me what kind of parts I'll need.

I already have Stellings dry headers. What is the bore/stroke? Can you recommend a CNC program for the heads. Which Dart block, tall deck, splayed main caps? What cam? What intake? Roller timing chain or belt. I have all accessories for a N/A in my 509's
