Oil pressure after rebuild...

Okay, just got my rebuild fired up, and minus a slight oil leak (I need a new rear oil pan bolt, I ran mine over with a hoist, so I'm short one) everything seems great. I filled the cooling system (which seemed to go very well) and it sits right at 190* after warming up. I don't have a radiator fan on it, so I didn't run it very long, about 5-6 minutes, a couple of 1/2 throttle runs.
My oil pressure at idle after warm up is about 42-43 psi, and it went up to 65 psi at 1/2 throttle. This seems pretty good to me, but this is my first LS1, and first complete rebuild, so I'm perpetually parnoid.
Also, any bad sounds I should be listening for? I hear no ticking or knocking, but, I'm still new at this rebuild stuff.
Thanks guys!

edit: Oh, I did run it at idle, with a few blips now and then for about 20 minutes on the very first start.

Well, just as an update, after a little more break-in, I seem to sit at about 33 PSI or so on a hot idle (780 RPM, give or take) and it still runs up to about 65-70 as I get over 4500 RPM, so I think I'm good as far as that goes. My oil pan (or my re-reinstalled rear main) is still leaking like a damn sieve though
, so I'm pulling it out AGAIN tonight to recheck everything. I think it must be my oilpan-rear cover point, as I KNOW I put the rear main in dead-nuts on. We'll see tonight.

Heh, just FYI. I was just updating this thread for informational purposes.
(If you notice, it was 2 years old...)
I don't even have this engine anymore. I've had another 5.7L, a 6.0L and a 5.3L in it since then. I'm currently putting together a forged 370" motor with an L92 top end for big spray.![Winky](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_wink.gif)
I am building another RX7 with the engine from this thread (new oil pan) and a T56 in it this spring. Won't be the "fast" car though.![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
Another random bit. After my old (ebay purchased) gauge died, I bought a shiny new one from JPH here, and it works like a charm.
