Brazilian Dodge Dart 76 (similar to 69 usa)

thanks gdonovan. Tomorrou I will take a shot of my engine to check if brazilian and american 318 la are different...

Now I know why I was having difficult to buy plugs from ebay.. because I was looking for a different than yours!

See attached picture of RN12YC, this is the most common small block plug from 1967 till the late 80's (longer if you count the 2.2 engines)

340's used RN8YC if my dusty memory is still working right..
