So, I’m in the process of rebuilding a 302 J code motor. I pulled the camshaft and have been trying to identify it. It’s a Ford camshaft (has the Ford oval stamped in it), but the two letter code looks to be GD (the D is actually backwards). I suppose it could be D9 or D6, it’s kind of difficult to read. But, that’s only part of the question.
I got my micrometer out and started measuring. I’m not done with that yet, but just out of curiousity, I measured the journals; like 5 times. They’re different sizes. 2.02xx to 2.08xx. I find that odd. Then, I check my maintenance book and sure enough, they’re supposed to be different sizes.
Now, for my main question. Why?
My book only calls out the varying sizes for 302 camshafts. The journals for camshafts for the other engines are identical in size.
Ok, back to measuring. Hopefully, someone can answer that. The curiousity has got me.
Thanks,
Greg
