Nope, not together yet, waiting on a new tumbler and retainer - which I almost got out without breaking. I was on a mission when I got to it but just didn't have the touch and cracked it.

HSR vacuum hose routings

85 4+3. I had to have my engine rebuilt from a blown oil ring, so I brought it to a shop to rebuild. I already had the intake off, so they had to install, and I think there may be a vacuum issue. ...

It had to be cleaned up more than .030, so he took it just enough. .0037 is spec clearance. He did have the pistons, and has used them before. May shed some light on why it took so long for him to...

I called him today but he wasn't there at the time, and I got too busy to call him back. I didn't want to pay for a sonic test, as .030 usually cleans it up as most will agree. Hence, no .040 over. ...

Anyone heard of a .035 over engine bore?

My builder went .035 over - not .030, not .040, but .035 over. We discussed a .040 over, but I decided against it. The reason for the build was an oil ring failure. Not that I'm complaining, but...
