Pre-Assembly Part 1

So, the components are back from the machinist and I've started to prepare things for assembly.
 


Today, the bores were checked for cleanliness.  Wiped down with a white shop towel.  All clean, so a fresh coat of Marvel Mystery Oil on the bores.  The hone finish was right where Total Seal recommended--Rpk: 10, Rk: 30; RVk: 35.

Next task was deburring the piston skirts.  A few of the custom Ross pistons had been touched with a die grinder to get the weights equal across the set.  There were some rough spots on the skirts, which I smoothed with Cratex rubber abrasive.  A quick scrub with soap and the pistons are ready for assembly.

Next week, I plan to install the crank and pistons into the block.  Stay tuned.

  1. So, just ran a couple ARP cleaning taps through all the threaded holes in the block. Not terribly exciting, but required nonetheless. And for my hour of work?.... A nice blister on my forefinger! Going to scrub the block tomorrow one last time and get ready to stick the crank and pistons in.
