I appreciate all the comments. The motor We pulled had 127,000 miles ,she ran great ,the problem was that when I stopped at a light oil pressure would drop below 5 psi. I did connect a mechanical test gauge were the pressure sender screws into the head to verify this.I have the updated bypass piston and screw. Oil sump was clean. In the filter I see plastic and what looks like cooper so I assume the bearings for the crank and rods are going.I have had the car 3 years now and this all started after the first oil change i did . I went to the recommended 0-w 40 Mobil 1.....So I assume the seller put heavy oil in to mask the problem.Anyway this car is my daily driver and I don't want problems I have replaced all the suspension parts new coil overs new xenon head lights new leather seats new glass window top new rotors and breaks all new stainless exhaust with 200 cell headers cat deletes I want some piece of mind that I go on a 2000 mile trip and she will make it back. And now I have a good core motor to make it into 3.4 or larger if possible.Once again thank you all you making me feel better about my decision I don't see any compelling info to pick one or the other It is all based on opinion. I can find no factual information as to any being better than the other.Thank you all.On a side note how lager can a 3.2 base motor be turned into is 3.4 max?Thank you all this forum is the most valuable tool we have .Thank you.
