Which engine would you pick?
#21
Seems conservitive with the Hp.
I would tend to stay with the low compression.
I case you get bad fuel and or can only get
low grade fuel.
Compition Marine Center builds a nice 572 ci that
runs on 89 octane. Dyno's at 750hp.
St. Louis MS.
636-946-1182 Ask for Chip
Everything is done in house, you name it.
Engines, machine work, paint, glass, carbon fiber,
interior , transmissions, drives.
Alot of exotic hardware
They have been building engines for MTI also
from what I understand.
Good Luck

Well, I guess I'll chime in here.
Personally, I like #1. Everything on that motor is better than #2 except for the intake, which is equal to or at least very close, in my opinion. The super victor is a nice piece.
You can run 91 octane on 10.5/1 with a 140 or less T-stat, cooler plugs and aluminum heads with no problem.
Just to give a difference of opinion on oil. 10 qt. is plenty of oil. The thing that matters most about oil, is temp. Keep it around 220*
The only down side to it is the blower thing. If you decide later to add a blower you would want to change pistons. Another may bad gas thing as well.
So, if you plan on putting this motor in and staying with it for a long period of time without changing anything, (ie: blower) I suspect you'll do just fine with #1. Just some valve spring maint every couple of years, depending on how many hrs you put on it/run it, and then the normal stuff during the regular maint. intervals.
As far as dyno numbers, they sound just about right to me with those cubes, r's and compression. On that point my opinion is to keep it around 5500 r's which may call for a cam spec adjustment.

CMC ( Compition Marine Center ) is/was working
on getting a website up. Other than that from what I
understand they do not do any advertising. It is all
word of mouth.
A friend of mine had an existing pair of 588's/ 900hp
redone/ freshend up by them. Hopefully he will finish
his rigging and be running them shortly.
Cosmetically they have some of the nicest engines
I have seen. Plumbing etc. is all laid out and very thought
out. They also have developed there
own wireing systems / circuit boards for a more
user friendly ignition system etc.
It would be worth the call way to much info
to share. Chip heads all the engine work and his
brother Jeff heads all the structural work, carbon
fiber etc.
When my friend was there, they had alot
of high end toys, Skaters etc. all having work done.
If your doing a new build (boat) they like to head they
project up with you and your boat builder. And have
stringers etc. set to there own specs. They then have
the boat delivered to there shop uncut. They then
do all the rigging and deliver one awesome product.

Cougarman - thanks, but its not a current project. Always thinking and planning the next boat. Hoping to find a builder who has produced a 700hp, no-blower, smooth idling package and has been doing it for three years.
Teague has a 620hp package like I discribed, but his 700hp package is still new - as is the others I have seen. Don't really want to be anyones R&D program.

Uncle Toys, Troy Dennis out of North Carolina has been building a 700hp unblown carb engine for at least 3 years. Seemed to Idle pretty good also. Very nice package, he'll go any color but painting isn't his strong area.
