I'll be going through the process of certifying my Engine Swap for smog purposes in Denver.
My truck is a Scout, but my 472 is, I believe, out of a 1974 Deville.
I believe they'll only require me to have the smog items that were factory on my '78 Scout (no cats or air pump fortunately).
1) However, just in case I'm wondering what smog equipment was standard on a Federal 1974 Deville with the 472???
2) Also, can I confirm the year of my 472 by deciphering the block stamping (not the casting numbers but the VIN type number on the front pad)???
Sorry I don't have the number handy or I would post it.
If anyone has a link for block stampings that would be a huge help.
