Dan hit the nail right on the head. Personally I wouldn't go any bigger than 565. You can stay with standard deck, rod angles are good and no goofy geometry on parts. I have 565's 9.3 compression efi's that make just a few hp shy of 800 hp. with a real good torque band. And on drives I wouldn't consider anything less than the scx. Already been down that rabbit hole. Any ways that's my 2 cents worth.

KWright,

Noted. Soaking it all in.

Thanks. Brad.

I personally would not put that much power in that hull. I don't know how much power someone has put in that hull, but I would not want to be the guinea pig.

This is about 90% of what you’re trying to do.



What you want is very custom, better find a reputable builder.

Watching his daughter racing right now. Of course I am.

I like the color of that motor,,looks sinister
