64-65 Hemi swap? Anyone do it with the stock K-Member?

I didn't realize your car was so far along. I assumed you were starting from scratch.

Check out Blake's videos here.
There is one showing the smaller Jeep alternator mounted in a different location. This avoids frame rail notching which is not the big deal everyone makes it in my opinion.

Also, he has a video comparing manifolds.
