bored 0.040 in over just to clean up bores, not for performance.
assembled long block plus intake manifold and Q-jet.
not yet broken in - do it your way! 60psi oil pressure via drill motor.
extras include: new headers, custom air cleaner, chrome valve covers, Fel Pro gskt set, +more.

That doesn’t match what you posted.

“New internals”. As in new connecting rods? Those would be aftermarket, not stock.
Same for .040” overbore pistons. Cast or forged? What dish volume?

Don't know those spcifics. Bought brand name stuff for basic .040 overbore cleanup.
Yes, I understand not 100% stock per se. Not gonna argue nitpicks. no attempt to raise performance.
Just wanted basic rebuild to allow installation in son's 72 Cutlass S.
Then he changed his mind.

May get more positive attention if you list out the parts that have been installed by brand and specs (or part numbers as otherwise available). Maybe post at least a couple of images of the assembly and even the major receipt docs to show what/when done

Not a lot of effort given the money you're looking for an otherwise generally sight unseen assembly
