^same here. My oil pressure was in the 90s at WOT when it was getting tuned.

wow... i think anything above 75 is too high ... it can spin a bearing

I think it was in the 90s. His hp tuners said something like that. Im not scared. Stock oil pump with 65k miles (supposed to be anyway) Only internal mod is an oversized cam.

If it was mine, I'd be driving it. Thats just me tho

mine pegged out 80psi at wot and lasted over 140,000 miles of 6900-7200 shifts.

agreed with everyone above,mine idles cold at 65, warm at 55, WOT is around 80, so I do not think you have too much pressure. Maybe something just got screwed up in the alignment and torquing process, I know you said you checked that all, but I have seen people mess it up a few times actually.

yea i guess you guys are right ... my old 454 was always up in the 80 range never had a problem....

I am going to put a big dual oil filer relocation kit and a fat oil cooler see if the press drops ... and hopefully the leak stops if not then out comes the motor again

Something else is causing the rear main seal leak...I believe that the seals are marked "this side out", but it's incorrect, maybe someone can verify this. A new rear cover with the seal already installed is cheap though...

The newer seals are reversed from what they were in the past, the lip faces towards the transmissions, instead of inward towards the engine. It’s intentional, not really incorrect and it did make for easier installation on the line and normally works fine for daily use, but under boosted conditions and such, they suck. The oil will push right past the seal. It is possible to turn them around during installation and as Billy said, they are marked this side out, just disregard this marking and be careful installing the seal/cover.

yea i am out of options ... i guess i have to pull the motor back out .

I put in the oil cooler and a dual oil filter relocation kit i had layingaround

It helped the psi a lil bit ... it does not pass 80 anymore its around 60 idle-80 wot

Time to pull the motor

I don't think your oil pressure is high. It's completely normal. Just yank the trans and fix that rear seal and be done with it. I wouldn't bother yanking the whole motor out.
