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.

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.

Growing older is unavoidable but growing up is strictly optional.

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.

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.

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.

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.

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,

I got this challenge form Mark, the Guzzi man:
Wow... I am surprised Mark wants to do this... he has seen me in action, I am the energizer bunny when it comes to SL6 projects, I keep going... and going...

Seems like more free beer in Vegas for me! .... it's time to kick things up a notch!

"Ca-noe" slowed me down a little,still might fire mon.mark

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

hmmmmmmm. ....Ill jump in for a six of Full Sail ale......I hope to stuff the new motor into the Valaint today...mebbe fire it up.

Seeing as how you guys name motors I thought I would call mine "Queen Latifa" ....seeing as how it always seems busted...

I see Allen is in short sleeves.....its not that way here.....freezing fog this morning.
