Interesting info Jerry.
All the bearings fit tight,no loss of crush.
However when it comes to detonation "hammering" the bearings that has not always been my experience.
I have 8 pistons out of my boosted 440 streetcar that pushed the ring lands down,all the bearings were fine.
On the 440 in question I collapsed the ring lands and dished the piston top from detonation on #4 piston a few years ago[different block} and the bearings were fine in that one too...
I have torn down engines that have lost all the crush and the bearings are curled against the crank...
I can only assume there is different levels and conditions surronding detonation damage.
Can anyone explain how you hammer/deform a piston and not see it in the bearings??
Must be something I`m not looking for...
