Got new rod bearings installed at the clearance I want. Checked rod bolts for correct stretch. Now onto the mains

Put longer main studs in and it increased thread count in the block by two. It took away that mushy feeling when going to the final number on torque.

Did that change the housing bore?

I will let you know in a few minutes, re lubing the studs now.

It changed #1 and #5 approximately .0003 smaller, the rest no change. #2, 3, and 4 are four bolt mains, 1 and 5 are two bolt mains. All mains are cross bolted. I will scotch bright back side of bearings to try to regain lost clearance. Whatever it takes, the solid feeling is worth it when torquing.

The scotch bright fixed it

Will you be using "full groove" main bearings?

Not full grooved mains

I had to seek out a very experienced engine builders advice on of all things how to measure something. He got me going down the right path in a matter of minutes. The problem was, I had not applied the K.I.S.S. method of problem solving, you know Keep It Simple Stu....

It is so great that most if not all of us are willing to help each other. I did not ask him what the latest speed secret is because I'm still trying to accomplish the first one he shared with me. The straight and round tip!

Back to work.

From your first post from this thread. It has been the truth.

I admire everything about what your are doing except for how much it makes me feel like a slacker!

Thanks for sharing,
Bill

Im retired so my hobby fills most of my day. Racing is venue that us old people can still be somewhat competitive and I like that. I enjoy trying to catch up with all the great engine builders that have customers competing in the same class that I choose to run.
