oil pressure was normal. i believe like 70-75. never goes below that.
idle sits about 750 and when i did drive to get gas i never went above 3000.
probably was sitting for a good month. half the tank is fuel from a month ago the other half is fresh. plus about an ounce or so of that lucas fuel treatment.
ok then lets look at this rational
1. it has to be a rotating assembly to make the noise
2. it increases with rpms
so what rotates? crank , rods, pistons, flywheel, cam (short version)
I thought you built the engine thats why I mention rod bearings
but your bearings should be fine, they were not changed, so should the pistons
nothing found on top of pistons or one of the electrodes should show it
timing chaing and oil pump should be fine
nothing found in top end, springs , pushrods
so what does that leave?
go back to what you did.
intake headers and such
pretty sure you didnt drop anything so you should be good there.
so what do ya have left, lifters, possible empty lifters,
the one I sent to russia had sat for two months, lifters bleed down, he called same noise, ran it for about an hour or so , noise gone, sounds stupid , but its been a couple months and still fine
only other thing I can think of would be in the clutch area, but nothing that would sound like that.
could actually be one lifter not wanting to pump up and that could also be why it sounds like its not hitting all ten also
forget the bearings you didnt touch them.
top end good, plugs good, gas want do it.
I cant tell ya to crank it and let it idle for obvious reasons, but I prob would do that on mine
now you can as it is running , pull one plug wire at a time , see if the noise or engine sound changes at all, that will give you a estimation of which cylinder it is
