2 things. I am still thinking with your oil pump out pump the oil BACK to the pan and or the motor oil was too slow to drain back down fast enough to the pan.
Next before you even started the engine - what oil did you use and did you oil prime the engine COMPLETELY just before your first engine start up ? If so did you verify oil all the way to the valve train and draining back down. Hopefully you correctly and completely oil primed the engine just before your first start up. Had to ask

So I had near about forgot about this post.
Here us the latest, engine has been with the local machine shop for about 4 months now, cause they're slower than molasses, but do good work. What ended up being the course of action was basically a rebuild because the cam and crank bearing were in poor shape. Crank got polished and new cam is being put it, the last thing I will ever buy from Raylar. No damage to the pistons or cylinder walls. Oiling system has been a hurdle, they had to call a big block oil pump guru in Illinois for advice on the correct oil pump to feed the overkill oiling system, basically turned into a pump that might be found on a 600-700 CID monster truck engine...... Now they said I could has blocked off the piston cooling jets, but I like the idea of extra cooling.
So in the end, Raylar sold me an out of tolerance piece of crap that I should have had built locally from the start. This learning adventure has cost me an additional 3000, 500 alone in an oil pump. Should be back in the boat soon. All that said, my local builder is saying now I should easily see 1000hrs or better out of this block, hopefully by then I'm on to a bigger boat.

I believe barrync bought the PSI built 540 shortblock from Raylar. Not a stock 8.1 GM block. As far as the Gen 7 8.1 block, the 10778 oil pump is correct. On the PSI block I don't know. I know a guy who did the PSI Raylar 540 last winter with no problems. I'll ask what pump he used.
No warranty from Raylar?

New, high volume pump, not stock, was machined so tight that the lid sided the gears when he put it back together. It spun freely prior to original install, but he is saying it probably didn't have perfect seal and wasn't pumping like it was supposed to at low rpm
