Not Ranked
The engines are the same the except for the stroke. **SAME**. But the 289 was build pre smog times. The 302 was built during the smog times and was layered with performance killing smog "stuff".
For a Cobra, you build the block, heads, cam, etc. from the ground up with performance parts anyway so there is no issue with the original smog stuff. It is out of the equation.
Except for the larger stroke, they are the same.
For a Cobra with a built up engine this is a non-issue.
