Good luck with the build. If you havent purchased the crank yet, i would personally opt for the centerweighted version for an endurance marine engine. Eagle makes it both ways, and not much difference in cost.
I believe the compstar, and molnar 4.25 cranks are center counterweighted

Nothing wrong with a 540 either. There a good solid proven build. Nothing wrong with any of the cubes mentioned. Maybe someday get the compression down on it an slap a blower on it. For now see if boating is for you and if you even enjoy it. It obsorbes a lot of time and can be frustrating. Who knows.... btw I know a lot of millionaires 10x over and most you'd think had a Friday night beer budget.

I appreciate all the input from everyone, and I can promise I am by no means an expert. Right now being a complete newbie in anything to do with V8's and marine performance is try to be a sponge and suck in everything anyone can tell me. After talking with Some of the guys from Molnar in Grand Rapids, Ateco by Chicago, Jim V and numerous others including my father in law I was suggested into building a solid 540 bottom end then upgrade from there. Luckily I have family who knows there way around american motors, which I dont being a european car guy in the past and they are helping build it and with machine work. But most of the people who know motors it seems they dont know marine stuff which Im learning is a totally different animal. Im just glad alot of guys on here and that ive met over the years are a wealth of knowledge. Im really wanting to build a solid 540 which i can add onto over the next few year until I decide to upgrade to something larger boat wise. In all honesty id rather have people suggest me to spend the money, spend it once and not have to do it again which will just cost me more in the long run haha
Obviously there's nothing wrong with a 540 but there's plenty more options and combinations worth looking into.

You'll be fine and respect what your doing. Your wants and needs change quickly in this hobby so chances are you will end up with a different twin app boat al together. Maybe not.... just depends on how much time you have for it and where you plan on running the boat. There's no end to hp and hulls. Next thing you'll be wiping drives out and so on. I think your starting out right and if you listen to Jim he'll lead u in the right direction. Doing a reliable budget build is fine. Also I noticed you must live in or around the GR area. If you need any machine work, balancing etc look up more power racing near Sparta. They dyno also. Good guys. I practically lived there for years.

Ive been hearing that now after I bought it..... its amazing how many shops either love Scat and hate Eagle or vise versa. Like More Power he recommended a bare minimum of Eagle stuff and no Scat, then the guys at Ateco say skip Eagle and they use Scat..... The part that blows me away is there all forged in the same place for the most part its just the quality control once it get to each company here in the US.

Scar cranks always seem to come in better then eagle as far as clearances, my eagles are all over the place... one engine the rods are all close the other they are a spread, all within my spec likings but it's annoying when all should be the same..
