venturing to the other side. Need Suggestions

The '67 Mustang is one of my favorite Fords next to the Cougar Eliminator. I think it will be a cool winter project. My swapping knowledge is limited to Mopars. I took three tries to find correct fitting headers to fit a 351, 4 speed in a '67 Stang. I don't think this would be an issue if the original 289 was used.

I had a '66 and a '68 so I'm right there with ya (btw, try fitting a cleveland into a '68 if you really want some fun lol)
