Off the engine topic at the moment and for the record focusing on the 64'-65' B-body crowd, I weighed the two extra factory steel sedan post doors that I now have.
With absolutely nothing in them and just the shells, they both weighed in at 77 Lbs for the pair or 38-1/2 Lbs each.
I gather my doors are somewhere in the park of 30 Lbs each. Still heavy in my book.
Oh well, back to this engine feathering that has spawned some rather interesting facts and or fictions.
