I recently discovered why the one engine was pulled last night. I plan to pull the other engine that is in the car currently to try and get it unseized tonight. The top end of the first engine was "good" and intact, it was definitely dry and in need of cleaning. Lifters and cam seem good as I don't know if I can say the same for the other engine right now.
Once I can hopefully confirm that rusty lifters are what is stopping the second engine from turning over, I can likely piece together a good engine with all the parts I have right now without having to find a good machine shop around me.
If I do decide to stay with this platform though I do have a nice block that's ready to be built and a crank that is ready/needs to be ground down to allow more generous oil clearances. I need to grab my micrometer to see if it is salvageable though.
Nice view of where one of the rod bearings from lucky rod #6 ended up.
You can even see the height of the groves left by the mains on this journal, not good!
