Which vender actually built the oil pumps? As some had no problems, and others had many, were different venders involved? Was told that the AMC designed oil pumps were better, but my 352 engine for the Hudson blew up at 75,000 miles. Engine always had valve train clatter. Engine oil was only half quart low and main bearings went. Engine has been rebuilt and running quietly for 5 years, but do not know what oil pump rebuilder installed.

Is that alternate oil pump the same that PI was selling for years?

Now what is the horsepower rating on that engine with fuel injection, and is it a 352 or 374?

The rodders are really going after the step-down Hudsons too, and the National club is encouraging it. I don't get it.

Was worried that Packard could have sold leftover '55 engines to AMC for '56, but that was not the case, as number is 6480406 CD on middle exhaust port.

Screw broke off of the center of the choke cover. Took out, cleaned and re-gapped all the RN14YC Plugs, which were covered with black soot. Engine runs a lot better and smother now. Will take off the Rochester when time and $ permits, and have it rebuilt and have the jets adjusted, if I can find a competent person to do the carburetor.
The engine oil gets black and thinner after driven about 100 miles after an oil change, so suspect some gas is washing down the cylinders.

Sorry for all the technical questions here, but still trying to have the 1956 run correctly.
The ultramatic quadrant which is on the top of the steering column, the pointer is out of alignment. It is the twin ultramatic with a dot and a slash. Cannot figure out which gear it is in as the pointer reading is to the right of each mark. Is there any way to adjust this? There is a screw holding it on the top cover, of the quadrant on the narrow part facing the dash. Do not know if Packard factory and AMC are different here. But have found out from working on this car that both companies had things the same way, and used the same parts.

Interesting topic, but my computer is blocking it also with a red screen proclaiming "unsafe".

This might be a dumb question, but I always wondered why the company was called "Studebaker-Packard" instead of "Packard-Studebaker", as Packard purchased Studebaker, they should have had top billing.

Don't forget to get the new "updated" oil pump.
