66 valiant 170

Edit* I noticed a tab under the #1 plug and it says B 170 0119. I’m assuming the last 4 should be the same as the last 4 of my vin?

The B in the pad means it is a 66 motor , A is 65. As for the numbers matching the vin, I doubt the factory worried about that at all.They used what was available . Generally if it's within 3 months of the build date it's what it came with.
