One of the blue ones s/b for the rear road draft tube for a TBird.  I think it's the middle one on the right.

I’m thinking that the gasket for the valley cover mounted road draft tube is not shown as it’s considerably larger in diameter than those that are pictured.  Here’s what I come up with for where some of those gaskets go.

I cannot help with the rings but if you are using the early edtion Eckman book  do not use the photo of how to install the timing chain, it's wrong. I forget the number of pins between timing marks (12 I think) but the picture shows them on the wrong side of the engine.  If your helper is not used to Y blocks he may want to line up the timing marks, dont to that either. Thats not how it works on a Y block

I think that was a good install guide on Ted's thread, use it and you will have no problems

thanks for the comment, I have that part well pointed, but since you comment, I will use Rollmaster red series and the camshaft that puts in the image below, the advance will be 2 ° as indicated by the paper, this is going for Ted

While the camshaft has 2° of cam advance (4° at the crank) built into it, there’s no guarantee that is where the camshaft will install if just putting the crank gear at zero and going with 12 pins between the marks.  Manufacturing variances in the various parts can have the camshaft installed far from desired which is why you must degree in the camshaft.  When degreeing in the camshaft, target for 4-6° at the crankshaft.  A bit more than 4° may be to your advantage as a new chain will stretch some initially thus retarding the camshaft some.



Thanks again, I will go to 6th then for my application.
On cleaning and lubricating the camshaft and lifters.
I suppose that the distribution system will happen the same, it is impregnated in grease for its conservation and I will have to wash it and then lubricate it.

...I forgot a question, the camshaft is impregnated with a kind of grease, for assembly I have to clean it before?

You will need to clean the camshaft before using it.  The grease you see on the camshaft is a preservative or protective coating to keep the camshaft from rusting during storage.  That coating is not a lubricant.  As a result, the cam needs to be thoroughly cleaned when it comes out of the box and then the lobes coated with the moly lube supplied with the camshaft before installing it in the engine.  Coat the bottoms of the lifters with that same moly lube but use only engine oil on the lifter shanks.

Thanks for the comments, I have checked all the rings and they are all within 0.015 ". I forgot a question, the camshaft is impregnated with a kind of grease, for assembly I have to clean it before?

...On the axial games and the clearances, I have read:
crankshaft end play 0.001 "to 0.006".+ Camshaft end play 0.001 "to 0.006". Maximum clearance between rods 0.019 ". Is all this correct or should we add something new?

As a general rule, it’s better to be on the loose side rather than the tight side when it comes to clearances.
 
I’m good with up to 0.010"-0.012” for crankshaft end play.  I prefer 0.004”-0.006” for the camshaft end play.  No less than 0.010” for connecting rod side clearance while I target for 0.025” rod side clearance on the performance applications.  Keep in mind that having additional rod side clearance has no effect on oil pressure.

Another question I have is about the position of the rods in the motor because the marks are not reliable and the previous assembly is not if it was adequate, the grooves where the bushings are fixed is the part that goes to the outside of the block ?

For the Ford Y, the bearing tangs face the outside of the engine or away from the camshaft.  If the rods are numbered correctly, those numbers will also face the outside of the engine or away from the camshaft.  The double check for this is to look at the bearing in the rod.  When the bearing is properly positioned on the journal, the bearing will be offset in the rod away from the journal’s side or edge.  By design, the bearing is offset in the rod so that the bearing does not contact the journal radius at the edge of the journal.
