stumped with all you have checked and done it should be solved how big is your cooler .I would normally say it was a timing issue but you have had it check ,oil lines sound like they r fine and a large oil cooler.Do you have a lead foot.lol I will make a call for you tomorrow and ask some ?

 

[cont520]

Is your motor breaking down/Maybe lean

 

[david]

timing set at 23 degrees it has a 11 by 11 by inch in a half cooler i can baby it and it will still get got just not as quick
