wifey had a 1600 pushrod in a '71 and later, i got a '72 (IIRC) with a 2L OHC. father in law left us a 2.3L pinto wagon (OHC). learned some of my first wrenching on them. bought the 72 with a worn out cam (used wrong oil), replaced cam, drove many free miles. big repair for my skill back then (still big for my skills today!!
) 1.6L used in some british cars too i think
