ok. Be working in the basement. Do you think cold tools might show wide clearances.
As long as everything is at ambient it should be ok.
I worked in a shop that had a huge roll up door on the east end. During the winter, when the wind was blowing, the office retards would open that door and in a minute you could start to see ambient temp starting to tighten up the bores while I was honing the blocks.
Keep everything the same temp.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
