And as I mentioned above, I don't blame anyone for thinking the 455's were transplants. That's what was printed in books and magazines for the last few decades when discussing 68-69 H/O's. When more people started doing some hardcore research into Demmer (not just tallying up production figures for H/O's), they discovered that the 455's were truly installed by Oldsmobile at the plant. Doc Watson verified that on TV. My guess is that the story of the 455 transplants was originated in 1968 by Oldsmobile in order to prevent any friction with GM management for using 455's in A-bodies.
Olds Plant Manager to GM Quality Control rep : "No sir, I don't why these engines are painted red today."
The 69's had a bit more work done to them (cosmetically) than the 68's. The 68's had the paint job, emblems, and a W-30 OAI setup, while the 69's had the paint job, emblems, decals, unique hood scoop, rear wing, special outside mirrors, head rest stripes, and a unique air cleaner setup. I love them both.
