What in this engine kicks it from 330HP to 425HP? Was this made specifically for ski shows? It's pretty rare for a 2001 hull, unless your name is Joe.

Ken,
I heard about this boat through mike. 05 210. I believe when Mike was dropping his boat off for the season he spode with the owner of NECC. He told me it came in on a trade from someone who upgraded. Mike told me that the owner of NECC had planned on keeping that one in their personal vault and not selling it. I guess everyone has their price! I am pretty sure has some knowledge of the history on this motor. I know that the motor is not a reverse rotation motor like most other CC's so that is the first way that this thing is capable of the 425 hp, by making it more realistic for CC to drop off the shelf performance parts into the motor. I am pretty sure it has rectangular ported heads vs the peanut port heads that your "330" hp 454 came with. Because of it being a standard rotation motor they probably used a bigger cam and some slightly higher compression pistons. 95 hp sounds like a big increase from a numbers stand point but these bbcs make hp pretty easy with some basic improvements that PCM should have made. It would be interesting to know exactly what changes were made. But I bet a nice pair of hi-tecks, and a full roller set up would take this beast to a whole new level. Sounds like a good starting point for Joe...buy it up buddy! ------------- "I'm planning to bring my girl that rides on a trailer with me and leave my girl that complains about camping at home" |

PS: Id want to see some paperwork before buying this thing at that price based on just saying its a 425 HO motor.
After staring at that motor over and over again I dont see any differences between the 454 in my boat and this one 
Not even an intake manifold difference... ------------- "I'm planning to bring my girl that rides on a trailer with me and leave my girl that complains about camping at home" |

Thanks, Eric. The boat reminded me of yours for a moment, but yours is definitely cleaner! You would think somebody would have kept much better care of this boat, especially being very rare. Joe would have a field day upgrading this engine. He'd get another 100+ HP out of it.

That's what I'm saying. There's no visible difference in my opinion. I figured it would look rare, just as much as it is rare.

By the way, they advertise the boat as a 1986. It's a 1985. Minor detail... ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1052&sort=&pagenum=4&yrstart=1986&yrend=1990" rel="nofollow - Nautique 2001 |

I was thinking the same thing also ken that it was an 85. Based on the interior and the dash. Good eye.
My boat is definitely cleaner but no where near as clean as your 86. Id like to be the first customer at "Kens Boat Bath" ------------- "I'm planning to bring my girl that rides on a trailer with me and leave my girl that complains about camping at home" |

the merc 390 hp came with big ovals, brass aluminum coated intake and roller rockers...if i remember correctly, it still had flat tops in it...im sure the power came from that combo and the cam ------------- "the things you own will start to own you" |

For the price of a gasket set I may find out how a lefty wants to act someday. Time will be the limiting factor. From the reading I've done, a roller cam is a big part of the HP equation. So spend 2K+ on a custom roller cam or spend less adjusting the hook and have a world of parts to choose from? I wonder if anyone here knows the production differences on the RH vs. LH boats? ------------- http://correctcraftfan.com/diaries/details.asp?ID=2331&sort=&pagenum=12&yrstart=1986&yrend=1990" rel="nofollow - 1988 BFN-sold "It's a Livin' Thing...What a Terrible Thing to Lose" ELO |

Mike also mentioned this boat to me... I believe Craig Warner (the dealer selling the boat, formerly NECC) was the one who originally installed the HO 454 in the first place. If he says its HO, then it probably is. A LH prop would be a good clue though.
Im a little surprised not to see a slightly taller intake or a dual feed carb on there. One would think that motor would require more than 650cfm to breathe. I thought all 4150/4160 carbs larger than that had the dual inlets instead of the transfer tube between the front and rear bowls. The topic of the 454ho has come up a few times on here. PCM only published the 390hp figure as far as I know. I wouldnt doubt 425hp, as that was the common output of the GM LS6 crate motors, which I believe this motor shared a lot in common with. Basically, it consists of rectangle port heads and an intake to match, along with a decent sized cam and 10:1 compression. Im assuming that the larger cam is what made it a LH only engine. I believe most (if not all) of these engines were dealer installed- so Im not sure what the factory's stance was regarding rotation vs. hook in the hull. Id like to drive that boat just to see how it behaves. I dont doubt it would be good for ~55mph if its a true HO though. Greg, roller is definitely more efficient than flat tappet, and it will also allow for greater ramp angles- so they can definitely make more power... but I dont think the number is huge enough to justify dropping $2k+ on a custom roller blank. Especially at the power levels we're talking (~1hp/ci). Flat tappets can still make big power. That being said, if you go forward with that project (custom roller) then let me know- perhaps there are some economies of scale that would affect pricing on multiple cams? ------------- |

Again from reading(and studying the posters), it seems like the roller cam is maybe not all that by itself, but more of an enhancer for a given set of performance parts. The RC lets the other parts 'be all they can be'?
I really don't know...yet. I'm also not going to put that kind of money in a custom cam. What would be fun is, like you said, drive one and see. I have most of what I need to build another stock engine, and then the tale would be told. ------------- http://correctcraftfan.com/diaries/details.asp?ID=2331&sort=&pagenum=12&yrstart=1986&yrend=1990" rel="nofollow - 1988 BFN-sold "It's a Livin' Thing...What a Terrible Thing to Lose" ELO |

I think Tim hit the nail on the head. Kinda small a carb for 425 ponies!
Currently I am building a high reving 427 with big oval closed chamber heads that will require at least a 750 CFM double pumper to feed it and it will be right at the 500 hp. More than likely hype, is Craig selling the boat? ------------- Hobby Boats can be expensive when the hobbyist is limited on their own skill and expertise. 1993 Shamrock "fat" 20. 2008 Nautique 196 5.0 |

Craig is selling the boat- so if he says its a HO, I believe him. Strange about the carb though... our BFN basically had a HO combo (LS6 long block with the baby RH cam) and it liked the 750cfm just fine.
Greg, like I said, a roller will have a longetivity and slight performance advantage over a flat tappet- but Im guessing the difference wouldnt be tremendous at the relatively tame power levels we're talking about. Custom cams should almost always be selected last, as their purpose is to optimize the other parts relative to the goals of the build... and that is true whether youre talking a flat tappet or roller. ------------- |

As far as outright performance, a roller cam won't make a huge difference over a non roller cam.
That carb does seem small and single feed w/ transfer tube seems like it really is not proper for a motor with that much supposed hp. ------------- 78 martinique- refloored, reinforced, stringers re glassed, re engineered interior GT40P heads Edelbrock Performer intake acme 4 blade http://img.photobucket.com/albums/v64/horkn/fish/nautique.jpg |

Apparently his personal vault has a hole in the roof. Do you try to sell your car without at least running it through the car wash?!!? The condition of the rims on the trailer alone would be a deal killer for me!  ------------- -Adam 1973 Skier |

I'll have to add, I did borrow a carb off of those 390 hp BBC's to install onto a 5.7, the carbs were identical (merc obviously) it appeared to be in the 600/650 cfm range.
I think the 10:1 comes from the closed chambered heads also???speculation Jodi. i have a pair of 427 heads and intake, do you remember your casting numbers? been saving them, for a rainy day. btw, Bob 440-667-6438, he is the guy with the Casales ------------- "the things you own will start to own you" |

Eric, I did do a casting number research but can not remember what the numbers were and I do have two seperate casting number heads though the results were the heads were consistant with 68-69 396/427 360 hp Corvette, they are currently at Cylinder head service here in PC getting hardened valve seats new SS valves and new valve springs I am putting it in my Rayson Craft as a superstock class correct motor. Thanks for the numbers on the Casales I will give him a call. ------------- Hobby Boats can be expensive when the hobbyist is limited on their own skill and expertise. 1993 Shamrock "fat" 20. 2008 Nautique 196 5.0 |

In my opinion, some buffing of the hull and some scrubbing of the interior, this will make a nice starter boat for somebody. Great conversation piece. I don't think it will last long!
I would love to hear this thing fire-up. Must have a unique exhaust tone, being a HO motor. Ken ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1052&sort=&pagenum=4&yrstart=1986&yrend=1990" rel="nofollow - Nautique 2001 |

?? Not sure I understand where you're going with this Adam. I was just clarifying what Craig told me when he got the boat. When he told me he took it in on a trade I asked him what he wanted to get for it and he said I'm not sure, I might hang on to it. Apparently,he has decided not to and I'm not really surprised. He already has several CC'c that he does not have time to use. I do not think that his decision not to keep it has anything to do with the boat's "condition". I felt that Eric's post may have made some assume that he is not keeping it because of some issue with the boat, and I don't think that it was intentional on Eric's part at all, so I wanted to clear it up.

The best BBC casting number archive Ive found is http://web.archive.org/web/20080513040220/www.mortec.com/bbc.htm" rel="nofollow - Mortec . Gottaski said he skied some 2001's with the HO 454. Some had regular 3" exhaust with muffs, others had straight piped 4". This one appears to have 3". Once you start approaching 1hp per cubic inch, youre going to start needing some pretty serious (and expensive) modifications to gain large amounts of hp. To pick up the 75+ hp that would be required to push this 2001 to 60mph (as evidenced by Joe- and the BBC would have a weight disadvantage over his 408w small block), youre not talking "a few mods"... at least not simple (or cheap) ones. ------------- |

My bad fellas. I didn't mean to cause any confusion. Even at my young age my memory is pretty short lived (just ask my boss and my old lady). I figured Craig was selling it for the same reason Mike just stated, nothing to do with the condion.
Although I do think this thing could be cleaned up a little to warrant an 11k sticker price. ------------- "I'm planning to bring my girl that rides on a trailer with me and leave my girl that complains about camping at home" |
