You are wrong, see above, and below. You're not alone, the whole world has bought into this, but it is a marketing thing that makes more sense (still not accurate) with wheeled vehicles, definitely not boats.<br /><br />

You reached 67 MPH because of the changes you made and most importantly . . . Horsepower.<br /><br />This is my favorite pet peeve, and I have been in the engine biz for 28 years. Torque is extremely important, but it is horsepower that makes everything go if you care about speed. Don't try and separate them, horsepower can't be made without some torque, but torque by itself is almost nothing.<br /><br />BHP = torque x RPM divided by 5252.<br /><br />Remember, YOU can deliver 300 lb/ft. torque on a breaker bar. I guarantee you can't row a boat to 10 MPH, let alone 60.<br /><br />If torque was everything, you would prop for peak torque RPM. Try it. Your boat will suck

I'm not going to get into a p****** match with you.<br />If you want speed out of the boat...BB.<br />I've noticed that when 26 foot boats are built for speed...the manufacturers use a stroked SB.<br />The original thread was about moving a 266 hull.<br />NO ONE IN HIS RIGHT MIND WOULD EVEN CONSIDER A SB. The only reason that hull came with a SB was because the owner was to cheap to pay for power.

What did I ask???<br /><br /><br />I read your profile, sales<br />that qualifies you as one of the most uninformed people on the forum.

mkast, I'm not trying to be a basshole. Please reread my posts. I am seriously just sharing what I know to be true. This is a math issue. The latest small blocks (377 and 383) outperform carbed, stock 454's, in every aspect, power, weight and yes, even torque.

You asked for a vote -- I vote for the 383 with Fuel Injection.

Re: Need advice on new engine for rinker 266...

Let's see, that wasn't a question, it was a statement. Your little "pet peeve" is a crock.<br />You should call Mercruiser quick, tell them, "Torque doesn't move boats, horsepower does!" Your missing a whole market segment, displacement hulls. Don't use diesels that torque, use 1075 hp 502's, because horsepower moves boats!<br />Right now Mercruiser is getting 260 hp out of a 4.3 liter. Who on this board believes the same hull with the 260 hp V6 will be faster than the 260hp 5.7 liter boat, because it weighs less?<br />Horsepower is horsepower.

Re: Need advice on new engine for rinker 266...

OK mkast. I officially give up. Just remember my comment about your ability to make 300 lb/ft your ownself and maybe the light will go on. One last parting note: when you feel like considering things outside your head, take a look at a prop load curve. They don't come close to meeting peak torque. Yes, torque will help you plane faster as I noted above, but speed is made with horsepower . . . Period.<br /><br />BTW, I believe the lighter weight, correctly rated, 260 bhp horsepower combination will go faster if it will plane. Why do you think OBs are faster?

Whatever the origional poster of this thread does, is up to him. I will post as much as I can on the converison when mine is completed. I have a 97 fiesta vee 266 with a 350 in it, and am replacing it with a 383. my second choice was a used 496 off of the offshoreonly.com web site classifieds. it was complete, with 25 hours on it, and was listed for $7000 this day in age, i would not consider a carb motor, Fuel injected, computerized, is the future, and the only way to go

QC, you are an uninformed basshole... <br />Some people just don't get it & never will.....<br />BTW, my vote is for the 383 hands down ....JK

LMAO JK. Thanks

Re: Need advice on new engine for rinker 266...

to QC and HAUT MECOC-----to settle the torque issue... VERY FEW boats use a gearbox to get the torque out quicker,,,,, those are race boats that need to get down the quarter mile in a nano second quicker..... others just wait for the nose of that boat to drop down,,, this in itself is very antique...... boats have a long way to go to get to where cars are today...but we are improving. to think that the only way to make horsepower and torque is a BB think again look at what the auto factorys are doing,,, they are the future, all marine inboards come from them,,,i want the most HP i can get from the least Cu IN and the least hassle in installation, ive researched since dec 05 when i dropped a valve in the middle of the channel in the mississippi river,,,,, 40 degree temp,,, 8 mph current,,,,, and ive chosen the 383 over everything else... if you want to continue to argue on this,,, find a bar to do it at...<br />See ya at the lake Hudman

Re: Need advice on new engine for rinker 266...

hudman,<br /><br />JK (Haut Medoc) was agreeing with me and you . . . I voted for the 383 AND believe that with a CVT we could use very light, blown engines and really rock. You sir, and I, are on the same page . . .

QC,<br />You might find this instresting...<br /><br /><br /> http://www.perfprotech.com/home/flame-arrestor-hp.htm <br /><br /><br />Response: As for horsepower there is a general misconception in the marine industry about horsepower. Reality is that torque is what moves a boat, hp is what sells them. In most cases a flame arrestor is an inexpensive way to add a small amount of performance. The truth is that it takes a considerable amount of performance gain to notice it "Seat-Of-The-Pants". Depending upon your existing application and engine performance level, a flame arrestor benefit will depend.

Re: Need advice on new engine for rinker 266...

mkast,<br /><br />We have hijacked this enough, so I started another thread:<br /><br /> bhp and torque

 

[piratedude]

Re: Need advice on new engine for rinker 266...

to sum up posts it seems like 383 wins since hp is the same as a stock big block but lower weight and cheaper parts. I decided on getting a 383 built locally and not the merc reman 383 w/ fuel injection...i personally like carbs for the simplicity and reliability. fuel inject is nice when they work but can get expensive when broke. any advice on building up a 383 marine motor? what size carb? type manifolds? stock exhaust going to work? what cam? any expert advise is welcomed! thanks for all the input!!!

Re: Need advice on new engine for rinker 266...

You made one mistake poi. The carbed 383 will NOT have the same bhp as the 454 unless it is being built up by a high performance guy. The 383 many of us recommended, and claimed had even better bhp, is the MPI version . . .
