The Rebuild Begins

I finally got the rest of my motor back on Friday ...



Today was spent getting the block mounted on the stand so I could work on it , then on to installing the crank . Plastigage on every single journal , and every one was between .001" and .0015" . Turned smooth as silk! That turned out so well I decided to install some pistons . Ring end gaps were all just a RCH over .020 (spec is .010-.020 top , .010-.025



2nd & oil) , and all 4 rod bearing shells were right at .0015" . I'll install the other 4 pistons tomorrow , along with the new high flow oil pump and rear main seal (it's a one piece , the first I've worked with) and maybe the cam and timing set . "Having a great time wish you were here!"

What's your assembly lube?

I'm using CRC assembly lube #SL3331 . Moly plus Graphite , first run break-in lube will be Rotella T4 15W-40 . `1200ppm ZDDP , critical for flat tappet cam initial break-in . I plan to run Rotella T4 in this one because it has 1200 ppm ZDDP , and I use only Wix filters .

Red c**t hair . Usually .003-.005 " .

That one wasn't in the acronym dictionary and likely won't be added but noted for future reference.
