I'd order the valve grind job gasket set, it costs almost the same as the 3 gaskets you want and you get the entire set.

I'm not sure about the dished pistons.I don't know what quality of gas you get there,but up here I'm pretty sure everyone uses flat top ones to get the compression ratio up.One who would know is Alan, 81 nautique, he did alot of research when he rebuilt his.

dished are the same as the ones I took out.. here we get unleaded regula in the 87-90 oct range, special in the 94-95 range and premiun on the 97-100 ron...depending the brand...

the round damper is the only one available and it does not fit right, you need to space it regardless of what you are told.
no, you do not need to order the 2 piece fuel pump cams but you need the correct top timing gear to accomadate the 2 piece ecentric, your mounting boss is off center and the other style is on center do they use lead in the fuel in your country? |

got it, im sure there is a post somewhere,
when you get the damper put it up to the Flywheel and you will be able to see the spacing needed, it does not sit flush |

Seb,
The spacers Eric mentioned are simply flat washers but they are precision thickness. Here in the states, they are sometimes called "fixturing" washers. They have been ground flat to a uniform thickness. Yes, somewhere there is a thread with the thickness mentioned. .1875" ??? |

I guess that they are from some special material ss or hardened steel, not the regurlar washer? I wouldn`t like this washer to corrode in there...

Gary, I would think it all comes down to what compression ratio he wants to run. If he goes back with stock replacement dished pistons and puts gt40p heads with 59/60 cc chambers he will be in the 9.3:1 area which is fine on just about any pump gas. If he truly has access to 95+ octane then I would go higher and the flat tops will be the ticket. A word of caution for him though is if his engine skills are questionable I would stay as close to stock as possible. We've already been through pushrod length and I'm not sure that concept is solid in his mind yet, then with a non stock cam and flat tops he'd have to check piston to valve clearance also. I think it opens a can of worms the farther he strays from his current thinking. Stock pistons, gt40p heads and a proven cam and good to go. Sebastian, if you have a link to the actual piston you plan to use and it has the specs I can figure your CR exactly for you. |

Alan
I agree with you gas its fine here but I don´t want to mess things up so I figure my big upgrade will come out from the head+cam+intake upgrade..I´m not looking on higher comp engine to gain more hp... I want something reliable and bullet proof..and that possible to run it with any kind of pump fuel and not worried about getting premium.... As for engine kit is this one from summit cam from cam research cr266 intake edl2181 and the heads... rebuilt kit |

What CR are you running Alan? In my haste to install my heads I forgot to check my CR. Since the new heads are the same cc as the old,I don't expect any trouble. I thought you'd have to bring your piston to tdc and cc the cylinder to get the figures to plug into the forumla. |

Gary, I'm just under 10:1 now with the new heads. If you have all the specs of your motor you can figure it out,ie: Head chamber, piston dome volume(can be plus or minus depending on dome or dish pistons, valve relief volume,deck clearance,head gasket bore,head gasket thickness, bore, stroke and conn rod length. There are several free calculators on the net, I use the one in desktop dyno. I tried to look up the info on Sebastians pistons but they don't list the specs on the summit site and I didn't have time to call today. |

Alan...you give million dollar advice, stay close to stock, your not building a race boat that will break the three digit mark, build it in mind with the torque curve and economy...and most important of all reliability.....the hotter it is the more you work on it, and that comes from going through that learning curve. stock over .030 pistons, GT stuff and you will have a reliable boat....unless you get a chevy they there will be no worries. lol
sorry Alan, I really have grown fond of these little boy blues, its all in fun |

Well I started ordering the stuff!!! just hang out with scott and the cam is in the grinding process I got to speak with him actually, told me he also skis, that he owns a MC that its totally payed off (means its old I guess), finally turned out to be a nice guy...
Ordered from skidim the marine gasket set and misc... Just left the heads and the summit order... That I will complete in the rest of the day... Then just seat and wait... They will come in boat..so in about 30-45 i will have the stuff.. |

Seb, where did you end up buying the heads from? Hopefully you went with Tristate- the advantage to theirs is the upgraded valvesprings that you need with the new cam.
Whether you fit under the motorbox or not depends on 2 things- how tall the intake manifold is and which flame arrestor you have. Both of those are different on your set up than mine, so my guess wont help you much. |

Order them at tristate...that was my comment on the extra money....
for the intake I will have the performer 2181...and I have the stock flame arrestor (2 1/2in tall?) |

I think Tristate's price is well worth it since youre upgrading the cam.
You *should* be ok with motorbox clearance. My Stealth intake is roughly an inch taller than the Performer, and with a 2" arrestor I just barely squeeze it in. |

I think there's a chart on the torque/HP open discussion that sort of covers your rebuild.
just checked it and it puts you around 330hp at 5000rpms. Keep in mind HP ratings are taken at wot, what you want to check also is the torque curve wich is in my opinion is key for propeller selection for specific applications. |

Alan ran a desktop dyno for me and came up with 311hp @5000 RPM with my mods combined with the stock exhaust. With your shorter manifold you'll lose a few ponies, but 300 or so is definitely in the ballpark.

Kapla, I just realised that I have a set of "PCM" Autolite Spark plugs that my dealer sent by mistake, and are the correct ones for your new engine with the Gt40s and not mine.
I will not be using them. http://www.skidim.com/prodinfo.asp?number=RP030007 |
