Block out of square

Treblig said

I'm surprised that no one has checked their block (in the last few days) to verify how square a regular block should be. I have one I might be able to check......I bet it's square!!! Lastly, I wonder how much end play there is in the crank. If the crank in walking front to back as Wenger is checking for square it might make a difference in the reading??? treblig

Dang.. Just when I thought I was going to get something useful done for real paying work; you are an enabler, Treblig LOL. I have a 273 block/crank in process right now that is at the stage to be checked; never has been bored or lined bored or anything, with a new SCAT crank (which I hope has a straight flange!). Maybe this evening...

As for reliable machining... let's remember that Chrysler underwent a bankruptcy and reorganization while these engine were being built and went through 5-7 years of harsh cost cutting. If something went through the cracks in QC, no surprise. QC was going downhill at Chrysler even prior to the bankruptcy... you could see it in the fit and finish in the mid 70's cars, and I can clearly recall it was a source of public comment even at that time.
