The block bore was cleaned up and measured, sorry. That was after I took apart the motor I bought, local machine shop did that for me.

I am gonna take all the pistons to work and steam clean them then see what we have. The pitting you see is on the top ring, so IDK if thats dirt or what, but the tops of the pistons and the bores themselves looked great.

What kind of oil pump you running? Standard volume, high volume, high pressure?

Melling 155HV, loose bearing tolerances and a large oil pan.

The culprit, broken tab off the vortec distrubtor. IDK if they are meant to handle HV pumps or not, but, lesson(s) learned.

What's the looser bearing tolerances for when using a hv oil pump?

IDK.

I feel like an asshat, but I took a motor that was running, swapped a few odds and ends and reused everything. So I do not know clearances etc.

How's the lifter bores look that had that bad lobes?

How's the lifter bores look that had that bad lobes?

Not a clue, I sprayed the block down with WD40, and then bagged it up.

Will assess later when I am in proper mindset.

be sure to clean EVERYTHING that touched oil (valve covers, bottom of intake, oil pana nd pickup, timing cover, etc, etc). The metal missing from the cam lobes went all thru everything and in a perfect scenario was ALL cught by the filter but in the real world it was not.

Any comments regarding the intake port "breaches" and whether that is an issue?

[NightTrain66]

If it is open to head bolt hole make sure it is not open on other side of that hol to other port (cylinders 1/3, 5/7, etc). If it is connecting two ports that head bolt will need to be sleeved (use .502" guide reemer to enlarge the hole then install .500" brass tubing with loctite).

If it is just open to that hole it is just cosmetic as the boost will not go past the thread/sealant down into block or past the stud/nut on top either.

Was there anything different with that cylinder compared to the rest?
