To tell you the truth I don't remember it being all that "exciting." I feel REAL lucky that the oil and antifreeze didn't put us on the roof or some other antics.
When I pulled the engine, I removed the valve covers, distributor and intake and literally threw the rest into the dumpster.
To get the car on the road I found an oil using 67 440 with the "good" heads (didn't know it then) with cast adjustable rockers. I later re-ringed and freshened up that engine, and it ended up in a friends 74? Dodge shorty 1/2 ton 4x4 later
Before leaving the navy, that 440 went into my black 64, and I swapped a 340 into the RR. That is something Ma SHOULD have done. A 340 was an EXCELLENT combo in a B body. Ran with stock 383, and got 17.5 mpg doing it.
