spark plug threads
just curious.......
why are the spark plug threads on an american made engine, like the chevy 350, a metric thread? isn't every other thread on the engine an SAE thread or are there other metric threads on this engine?
when did chevy start doing this?
would a 283 from 1957 have metric threads (or was that befor the metric system came about?)
thanks and have a great day.....
