My block is at the machinist and he finally got the thrust surface cut. This was a challenge as it is very difficult to measure how much to cut off the new thrust cap. He is currently doing the line hone. The new 4 bolt caps are much harder to machine than the cast saddles in the block so this is also a challenge to prevent cutting to much off the block side during the line hone. To further complicate this process the front and rear caps are the original cast caps. The steel caps came about .050 too small compared to the correct bore size. The steel caps were put in a mill and the bore was rough cut to reduce the amount to be honed during the line hone. After line hone then it will move to boring the cylinders and moving one bank over about .015" to get more material on the thrust side.
