LOL...don’t feel too bad about screwing something up. Monday morning I had a short block together except for the oil pan. I had milled the pistons for the CR I wanted, and I assumed I remembered the combustion chamber volume, so I didn’t CC them again.
And...I was off by 5 cc’s. The only good thing was the heads were small, so I could save it.
I had to pull the pistons and rods, knock the pistons off the rods, mill some more off the pistons, clean all that stuff up and put it back together.
As of this morning, I’m now where I was on Monday.
I should have NEVER trusted my memory.
