I have pulled apart a couple 69 273s and neither had a steel crank, my 68 did have a steel crank.

And in the LA 318s I have never found a steel crank, 67-99. I have heard of other guys finding them in 318s but I never have and I have torn apart TONS of em looking


I am not causing global warming, I am just trying to hold off a impending Ice Age!
