oil pressure July 6 2012 at 11:44 PM		(Login 73torino17) Member from IP address 71.37.188.204


I was messing with the timing in the stock car motor today and I noticed that above 4k the oil pressure slowly falls off about 10psi by 5k. All of the clevelands I have built have done this. What causes this? oil pressure is 70psi cold idle hot idle is 30 psi and gets to 60 psi by by 3500, and then starts falling off above 4k down to 50psi by 5k. 9qts of 10w30
