I do the normal cleaning as I do on any engine before I start to assemble.
Core plugs all go in first followed by the Cam Bearings.  It is critical to fit the cam before anything else is done incase you have to resize the bearings. This one goes in nice and can easily be spun by hand.
Next thing is to install the internal oil line.
I make my own steel line but here is some more detail on how I do it.

 On the performance engines I drill out the main bearing feed holes to match the 5/16" oil feed hole below it and carefully chamfer and deburr the hole.
I am using Clevite Rod and Main Bearings on this one.  The Clevite brand seem to give us the best clearances but of course, they are more expensive than the rest. The rest seem to run a little on the big side up to a half a thousants. The clearances on both the rod and mains are right at .002".

Then a little Lubriplate 105 on the bearings and Assemblee Goo on the rear main seal.

I am ready to do this LV bypass feature on my 72 401, will be using A1 line material, I believe it is the same as Russel  just different coloring.

Will be running a 0.506"/0.506" hyd roller also.
How has yours worked out for you, flawless I hope.


Any concerns at all is well from the initial get go on it so I can know for maintainability purposes?
I believe the burst pressure "tensile strength on your steel line is 8,800 PSI or somewhere close to this. 

thx
Rob
