So not today, really Sunday, I put my bored .040 6.9 block back on the engine stand. Needed the stand for my tractor motor so just set it on the floor of my shop. Not out of the way either. Just right in the middle of everything.
So in an effort to get the shop more functional I did that.
Back story. I was well into building this motor when my divorce happened in 2012.
Crank been turned, heads decked, new valve guides and ported (by me).
.040 pistons milled .050 off the top. Works out to about 16.5 CR. (Yes I know, hard to start)
ARP studs. All gaskets and oil cooler kit.
Moose pump #4. (It's on the 7.3 currently)
Well this block has been sitting unprotected, 100% indoors for 11 years now.
The cylinders are pretty corroded because we get lots of humidity and hot/cold cycles. If your building is not climate controlled here, everything sweats.
So I tried honing one of them. It's working, slowly, but I have no idea how much it's going to grow before it's completed. May be too much to use it.
I may be looking for an unmolested 6.9 block in the near future.
