1968 Plymouth Valiant First Gen HEMI

It was a 392. The challenges are many but not "mission impossible", just a lot of mock -up and fabrication work.

Good luck with the build,

We have a member here with a 354 Hemi in a 65 Valiant. It was a very clean and nice install. The car is red. I don't remember his screen name, but he talked like the install wasn't all that bad.
