        Hmmm, wonder if that filter wasn't doing its job? Didn't you say it was dry/no oil in it?

          Couldn't the filter have a defect and not allow circulation?

            Again, based on the amount of bearing shrapnel in the Pan, I'm leaning towards the drop in oil pressure as a result of the screen on the pickup being blocked. The engine noise started before the pressure drop.

            I'm dropping the whole enchilada at the machine shop tomorrow. Hopefully he will be able to take a quick peak at the engine while I'm there....

              Small update - picked up the head today. Machine shop installed all new bearings. These are the only shots I can offer for now. But I will be getting back to work on the car now that I've checked off some "honey-do" projects

                Baby steps...

                Since it's been cold in the garage, I've been in the basement preping the motor. First thing was to check out the used short block that I'll be using {temporarily} until the original block can be repaired. Crank bearings look good. Rod bearings have seen better days so I pulled all the pistons:

                  I've been cleaning up the block (oil around the front crank and aux pullies) Still need to clean more (gasket surfaces, etc) and prep for paint:

                  I'll polish the rod journals and platigauge before I install new bearings:


                  I ordered most of the "stuff" that I'll need to put the engine back together. Got a good deal at Autozone for the oil pump ($42 with tax). The rest of the stuff should be in next week (gasket kit & rod bearings)...


                  That's all for now folks. As stated in the title, baby steps - but I'm moving along!

                    Yes, I see lots of copper. I guess it's common to see it like that with the majority of the wear on the one side?
                    My wife says it's a sickness...what do you think?

                      Oh, quick question - what at the torque specs for both the main and rod caps???

                        Yeah, I have no clue how many miles are on the short block. All the bearings with copper are the upper rod half (top) nearest the piston.

                        The nice thing is that the bores are in great shape with no ridge at the top what so ever

                          Good stuff there Professor Fleming. I cal'd my clicker tonight. It was off a "few"...

                          Start re-assembly of the "budget" short block this weekend

Attach a socket between it and your clicker wrench and clamp the clicker in a vice. Set the clicker to a specific value and then use the beam-type to verify/test/set the clicker. Error on the low side. For example set the clicker to 25 and see what the beam measures as peak when it clicks. Then adjust the clicker setting till you get say 25 Ft-Lbs on the beam. Do Step 1 on all rods. Then set clicker to 35 and test/adjust it again. Then do Step 2 at 35.

                            Huh... Clcker torque wrenches go out of calibration? How common is this? I've had mine for ten years, and used it as is when assembling my engine... Never been recalibrated.
                            If it ain't broke... Give me some time!

                              out of calibration???
                              My Dad ownd a service station back in the 70s... he said he's seen them be 10 ft pounds off in less than a month. (he had them calibrated monthly)

                                All parts are in so I put some time into the short block. Torqued the main bearings (installed a new rear main seal). Then I polished all the rod journals then replaced the rod bearings. Cleaned up the slugs and re-installed into the bores.

                                I checked the clearance on all the new rod bearings, all were around 0.0015:


                                Generous coating of engine assy lube and then torqued the rod caps per Mr. Flemings specs:


                                After all the slugs are in, installed the new oil pump and pickup:
