Yes I would like some more info on this too if possible. Is this something I can try or should I tell the shop who is balancing it? Thanks for all your work on this write-up it is coming along nicely. |

Thanks for the input, it really helps me edit the posts so everyone can follow what is being done. I added some additional text to the last entry on crank prep. My problem (a "good" problem) is that I have done a lot of these engine builds so what is obvious to me may not be obvious to everyone else.  DD |

Doc, in your latest update you say to use a late "large pilot" crank. How important is this for a mild street build? I already have my crank reground and ready to go but it isn't installed yet so if I need to make a change, now would be the time to do it. |

For a manual shift car, it really does not matter, as long as you have the correct flywheel. For an auto trans car, if you have a converter you like, that goes with the "small hub" transmission you have, then you are OK but if you ever want to change to a high stall converter, you have to go "custom" with the small pilot stuff. These days, I build all my SL6 engines using the big pilot cranks and use the adaptor ring when they go into cars with the small converter nose. Doing this gives me a lot of flexability if the engine needs to go into a different car later on. In your case, I would just use what you have and get the car on the road. DD |

Holy valve shrouding Batman. The pics with the head on the block from the bottom really shows just how bad a set of bigger valve are to close to the wall. Is the one head cut so much that it now has quench/squish pads that are even with the block deck? Maybe its just the pics making it look this way but that is a lot of cutting if it is. Jess |

That head has .100 milled off of it. Even with that heavy cut, there is still .080 of "step" before getting to the flat in the chambers. DD |

Doug you were talking about 1/2 x1/2 rod balancing. Do you lay 1 end of the rod on the counter and 1 end on the scale?? Sorry I didnt chime in earlyer I must have missed that post. Also is there a prefered method to storing a assyed block with out a head. Im having rust issues on bearing and machine surfaces while working on the head.(yhea Im slow) Thanks Frank

Yes, you can do "1/2 & 1/2" balancing the way you discribe if you can set-up so all the rods position in the same place every time. I have 2 little triangles that I use, the bases are double sided taped down and the peaks get positioned right at the inner edges of the large and small rod bores, right where I can see the edge along the bore's edge. There are rod balancing stands and scales available but the set is kinda expensive. As for storing machined blocks / cranks, spray or wipe them down with oil and put them in a plastic bag. If I store cranks "long term", I tear strips of cloth, soak the strips in oil and wrap / tie the oily strips around each journal, then bag. DD |

Can you post a pic, of this setup? I can't seem to visualize it.

I made one at home out of hardware store stuff and a digital scale. Look up my Rod Polishing thread. I know the ebay ones gor for a couple hundered. Hatch Engines who I have mixed feelings about for a six cylinder build, only charges $150 for a complete rotational balance so probably not worth it to buy a rod scale unless you want to do this several times (like Doug). I had to edit this. I need to give credit where it is due, I didn't come up with the scale thing on my own. I got it from this guy, http://www.angelfire.com/ca4/CorvAIRCRA ... lance.html |

Are you still working on that "ca-new" car you bought? You better get back to work on Guzzi... I am on a roll. I used one of my not so secret wepons today and had Allen pull the engine out of the Lancer while I worked on finishing my "ca-noe" engine assembly job.   If all goes as planned, we will stuff the other twin into the race car TOMORROW. DD
