Not wanting to piss in your punch but making 900-1000 Hp in a package that will live isnt gonna happen with a 250 Blower. Second, What are you going to run for drives. Not trying to be a buzkill but you are looking at dumping tons of money in a boat that will kill bravo based drives like prohibition is coming back and drives are the alcohol. Build some nice 700's and go have fun.Quote:

Luckily they lasted almost 6 seasons until I decided to abuse them (overheated the engine oil) on the last ride of this year. As far as the drives they will be replaced next year, with what? Who knows. Haven't made it that far yet. I do know exactly where I placed my spare bravo and a spare gear set. LOL. Cause I will most likely need it. Even if I go on the conservative side with 700's.Quote:

What I don't want to do is build engines this year replace the drives with something that can handle the power, next year and start completely from scratch on new engines the following year cause it don't quite go fast enough.
- I m good at that.... lolQuote:

Your boat also started with a staggered setup and dry sump six's. Now go get to learning how to be a good Gandydancer.....lolQuote:

Has anyone heard of or ran a Kings Crankshaft? They are USA built using timken steel. Talked to them today, very knowledgeable. I've been told to run a USA made crank by several. Callies, Lunati and a few others I've talked to say they are either not made in the U.S. or cannot confirm or deny they are or are not. Whatever that means. I'm guessing no. The King's crank isn't badly priced. Just researching a bit and thought I would share.

Sounds like you have a good plan. Your intake is for a standard deck right? Was intake for the 250 ever made for a tall deck? Just curious. You could put some spacers on it and convert it for tall deck use.
Never heard of kings crank. I'm a fan of the forged Callies or billet Bryant.
For not much more, you can get a windberg which is what we use. Alot of top fuelers and top alcohol cars use them to. The windbergs are also made in the USA.
Plan sounds good. If your engine build turns out as good as the boat restoration, then its going to be one sweet ride!
You are correct, my current intake is for a standard deck. It looks like the blower shop offers an intake for a standard deck that fits a 250 but, for $600.00. Since I will be upgrading blowers most likely sooner than later I am going to opt for the spacers at $125.00.
