    Number 3 cylinder imploded... Valves are very slightly bent, but pistons in a bunch of pieces in the pan...rod survived! Pin and pinch bolt are intact.

        So Where is the Crack in the Cooling System (Block) that caused all the Coolant in the Cylinders?

          I think the cylinder let go, and it was spinning fast enough that it shot up through the intake valve while it was open.

            Do the head gaskets have to be oriented correctly? If so, is it possible they were installed incorrectly and covering/exposing coolant passages?

              Or the broken piston knocked a hole in the block.

                  At what R.P.M. did things let go?

                    Dunno, no tach hooked up. I revved it up a couple times to clear out the carb, but nothing excessive..

                          HAHA...that probably puts you into a more common group within this crowd than most of us would want to admit.

                          On a more serious note...unless my memory has completely left me...the rods in these engines require a specific orientation. Any chance one was turned the wrong way? I made a quick review of the posts and don't see where anyone has mentioned this? I don't even know if the cap can be bolted up if the rod is turned the wrong way, but I'm just trying to make sense of how such a failure could occur on a newly rebuilt engine?

                          Those of us who have tinkered with these engines, either the six cylinders or the eights, know that they are ruggedly built and can take a lot of abuse before blowing apart, and especially the lower end. We have a select group of members who have built, raced, and punished these engines for years and can attest to their durability with great credibility. That's the reason I am so curious as to exactly what let go on yours?

                            I'm at a loss as to why the piston disintegrated within a few seconds of the first engine start. The only thing I can think of without being to see the carnage first hand is a major defect in the piston such as an unseen crack in the wrist pin area. I've seen plenty of failed pistons over the years, but nothing like that. Bud

                              Possibly swallowed a nut, bolt, or other debris that was accidentally dropped into the carb or was lurking in the intake manifold. Sort through all the debris and see if you can find something that didn't belong there.

                                Heck, all I had to do was bring a Studebaker home in any condition and my (ex) wife was not impressed. She never did ask about cost which is a good thing. When I had to sell as car for economic reasons, or if a car had to be pressed into service, I would say Studebaker bailed us out again and she would.
