Hi All!
Without going into all the gory details, it appears that my original 1966 390 FE block (from a Galaxie) has been ruined by poor machine shop work.  I have access to a 1962 390 FE block (from a Thunderbird)....and I was wondering if there are any major differences between a block from a 1966 390 and a 1962 390.  Thanks!

Hi All!

Just wondering if anyone knows if it's possible to get a normal pressure reading from an oil pump but not have an adequate volume output from it.  It's really a long story, but in a nutshell, we are rebuilding a 1966 390 FE.  We are now on our second set of roller rockers, roller lifters, and a roller cam.  No matter what we do, the valve train is still terribly noisy.  We also have run the motor with a cut open valve cover to see what's going on in there....and we noticed something very interesting.  The second we shut off the motor, we can visually see the pushrods on the open valves start moving.  We assume this means the lifters are collapsing.  Oil pressure is great...70-75 psi cold and around 40 psi hot.  We are using a Melling high volume oil pump.  I figured it's along shot, but I was wondering if anyone thought it was possible that the pump, although indicating good pressure, wasn't sending the volume of oil where it needs to go.  Thanks!
