Need some help on block issue.

[Jas89TTA]

I was cleaning the block deck and the top of the pistons today and noticed that when the piston is fully up it's not even with the block on both sides. On one side (front) it's evenly flat with the block other side (back) it's a little down in the bore still I checked the block with a flat metal ruler for flatness and it looked fine. I'll try to get a straight edge to check it the correct way but it's like this on all 6 cylinders. Is this normal or something bad I would have thought the piston would be even with the block on both sides. The heads checked out OK at Champion they were not warped, but I'm now concerned that the block could be warped or the rods bent. Thanks, Jason

I would say it's probably ok. I had a broken skirt on one of my pistons and it was rocking in the bore but in that case it would be tilted from side to side, not front to back. Look at your cylinder bores and itf there is no abnormal scuffing of the cylinder walls you should be fine.
