That would be 1.25 horsepower per cubic inch, which is obtainable, but I would bet not with your combination of parts, cam, heads, exhaust logs.  If I were building something similar for a customer, I would be more inclined to think possibly 1 horsepower per inch or less.

375 to 400 hp seems like it should be sufficient for what I want, hopefully it'll be enough to get going a little

bought a aed 750 hp body DP, built for marine use, I asked what the difference was between the standard and the marine other than the j tubes and a 100 bucks, the guy at aed told me that the marine carb was calibrated for marine use ....something about the fuel curve or some $hit, we'll see, but after researching on the net I have heard nothing but good from aed so I trust them enough to fork out the dough and give it a shot

 I am getting ready to put my motor in my 19' jet boat, the motor is a 396 with a decent cam ( on the higher scale of "mild" but not radical) the motor is balanced and according to the machine shop will make 500 hp no problem, I think realistically 400 -450 hp, I had a circle track BLP 800 holly that I had a carb shop rebuild with marine components, I ended up selling it because I really just wanted a brand new carb. I am now ready to pull the trigger and buy one, I'm not fixed on brand new, now after I see hollys are 500+ bucks, but I will spend it if I have to. my  question is what kind and what size would best suit my needs? 19' hardin caribbean w/ a berk "A" pump I am looking for a general all around perf and milage set up anybody else have something similar or experience with different carbs that can give me some good pros and cons? or just your opinion is appreciated too thanks, Mike

I really don't want to do this floor in my boat, I just put in a new bulkhead two days ago and I'm still itchin. I have all of the stuff to do the job, I just need to come up with some cash, I thought I'd throw this out there... I have lots of things I could trade for the work, snap on tools, snap on tool box, metal working tools, some parts, and partial cash if thats what was needed let me know if your qualified and if your interested. Not to be a dick but I'd like to see some pics of work that you have previously done, I know lots of guys that can do anything most of which I wouldn't let them change my spark plugs

hardin caribbean, I really don't know about what the impeller is, it's a berkley pump, I took the inspection cover off and the impeller doesn't seemed to be dinged up or anything, how can I tell  what kind of impeller the jet has?

yeah I'll probably just end up put the boat together, I'll post pic of the floor when I'm done

looking for a boat w/o motor, I currently have a project boat and am considering just getting something else and putting all of my parts in it, I have a 19' jet w/ a bbc and would like something comparable let me know what you got
