Had a CJ7 with a 304 and automatic.
Tires from a Walmart supercenter.
That thing would go through snow and the worst ice like nobody’s business.
On some level an automatic in a CJ sounds wrong.
I might have seen one set up with an automatic transmission. All manuals for me.
However these days with parts being the way they are, I would entertain a modern automatic with a floor shifter.
I have a rescued 304 but I found a cracked bell housing.
