And do it again and again!Oil pressure was good . I suspect debris. Time to clean , rinse , clean ,brush , rinse etc
Journals and pistons still look new .
Rod bearings have some specs as well.

Looking at the main bearing pics...im guessing this is a 340.
Folks tend to think that because the outside and major open inside areas of a block and head are clean when the come from a machine shop the parts are clean enough for assembly. That is not always true. Most machine shops do not have the wash equipment that really cleans and flushes the internal oil lines and blind bolt holes. To get those really clean, get a selection of nylon bottle and pencil brushes that are snug fit to the hole diameter and have a handle length that allows them to pass completely through the open holes from one end to the other. Then go at the oil lines and bolt holes with hot water and a good detergent like Dawn dish soap.I am sure it was insufficient cleaning by the assembler . Me ....
This time it will be very clean !
You should see all feeds through the hole in the bearing. The oil feeds the journal and as crank turns... more is drawn in..while the deflecting oil goes to the cam with the same scenario.Slotting the bearings is a good idea .
I drilled all the oil galleys and checked bearing orientation but I was still uncomfortable with the amount of oil getting to the rockers . So I ordered ball to ball oil thru pushrods and cup style adjusters . I still didnt see much oil at top end with VCs off running .
Which is one of the reasons I chose to pull engine and go thru it . I also wanted to redo ring gap to .018 from .016 as I wasnt sleeping well thinking about the smaller gap .
Everyone had pointed out what they see.
What I also see is lack of oil to the cam bearing at startup. Now look at your main bearing oil feed holes and the alignment of the main and cam feed to the bearings oil holes. Can you show the oil feeds at the mains with the bearings out? Is this an early 360 by chance?
Slot the main bearing holes!
Any dark sections of the bearings are showing lack of oil.
Yes you have 600 open on the cam, but its starving at the main feed for oil.
Ps, sometimes the bearings have blueish to them in areas from plating. Make sure thats not what you're seeing on the thrust.
Exactly.If the OP is using Clevite H series bearings that’s what they look like.
What did you do to loosen the tolerance? Oversized bearings?I got the short block back from the shop today . Bearings were to tight as were my rings by a bit.
New bearings and rings now .
Plan is to dyno it next. With Victor and Pro Dominator ( if I get carbs and linkage finished in time).
