Reply to "bore size Hypereutectic pistons"

Dear Larry,


My thoughts on minimal cylinder wall thickness:

1) I don't know that much and I do rely on people that build engines for a living for good advice on these issues

2) Personally and simplistically, I prefer all of my cylinder walls to be .125" or greater. Not easy to do, so...

3) My method is to have all of my blocks ( I think I have about ten in total ) sonic tested and then I pick the one with the thickest walls. Out of the bunch about three or four are good. About three are OK for street builds, but not big HP builds. About three are not usable without sleeving.

4) Whenever you really need a good block, then you can't find one. When you don't really need another block is the time that you'll find a good one. The metaphysics of machine shop metallurgy!


Warmest regards, Chuck Engles
