Re: Oil preesure ?

I had a 428 PI that would get 100 psi with a heavy duty oil pump. The pressure you mention is about right for a stock oil pump - neither too high nor too low. Sounds to me like the problem is the sending unit - not the pressure.

Re: Oil preesure ?

While your oil pressure doesnt seem to seem to be a problem, the rod knock you describe would potentially be a very major problem requiring an overhaul.
