273 spark plug mishap

HotLines said

Why would anyone use Autolite #85 spark plugs in a 1965 273 engine?

First off, the spark plug itself is 1/2 the thread length of a #66 or a N14Y for that matter..

Could anyone explain the reason for this?

Could anyone explain how this vehicle even ran and ran a thousand miles?

Thank you

OK, I'll bite and answer your questions:

#1 Why would anyone use them? Because they didn't know any better
#2 Why is the thread length 1/2 a 66 or N14Y? It was designed that way
#3 Why did it run 1,000 miles? Could be a number of reasons, one of which is probably dumb luck.

There, now your questions are answered. Hope you didn't expect more, since the first two were rhetorical and inane. While the third question could illicit an interesting discussion, it really can't be answered positively. But, given the tone of your first two questions, it's a good guess that your third was offered in the same spirit as the first two.

Next time, ask questions that really can be answered before calling the rest of us stupid.:violent1:
