            I'm going to guess that what he DID was wreck his engines. Twice.

            Removed/loosened his headbolts? Ran without cooling? Wrong timing?

            What engines are we talking about here?

              Hard to see the pics on my little itibity phone screen but i am going to say he didnt retorque the heads after a warmup or disnt torque them at all.

              It might be the alternator if the v-belt was installed in the wrong directiom

                      OK, I re-thinked the alternator belt!

                      (come on guys...... the belt was a :kidding !)

                      Loren, by chance was this purchased as a short block only? If yes, my answer is a "Where's Waldo" answer. Hint... hint!

                      Incorectly torqued cylinder head bolts!

                      BTW, the correct answer gets you a brand new 377/383 from these guys!

                        It appears to be affecting all cylinders shown, not just one, so it's got to be something "systemic" such as cooling or ignition type. If I had to guess cooling, I'd say forgotten impellers, forgot to hook up the muffs, or missed reinstalling a cooling hose or cooling drain plug?

                        Did they store their honda generator in the engine bay? Or.... If only they had bought a Sea Ray, they'd of had the newest power package. (

                          Did not torque the head down in the write pattern!

                            DETONATION.

                            But not from ignition....noooo....this baby cooked. It detonated BECAUSE of overheating.

                            This is a PERFECT example of my previous post about diagnosing the ORIGINAL cause of failure...saying "warranty" and us sending a new engine doesnt solve anyones problems, it just makes more. :surr

                              I think maybe he didn't torque the heads correctly or forgot to put water to the engine one way or the other. Enough suspense already. Gary
