For a while I have been having problems with the oil pressure dropping at high rpms. I've changed oil filters and it seems to help. A purolator will drop down to 30 psi at 5500 rpm, a fram to 40 psi, and an ac delco only to 50 psi. I'm using doug's headers so I have to use a smaller filter. The ac delco number is pf58 and I think the fram is 3829. I'm assuming that the problem is oil flow. I have the angled oil filter adapter. Will porting it out some help? I dont want to use a remote oil system. Its a 72 400 60 over in a 65 lemans. Any suggestions?
