Good work on the Cobra! And if you could provide a short example of its sound, that would be delightful!

Tom,
Very fitting plate, I picked mine up about 11 years ago and still holds true to this day, but could be much worse.

I was over the moon when they came out with the 7.3, I couldn't see spending the money for a built FE or SBF when I'd be deep into it and only marginally more power than the LS stuff I've worked with. I also couldn't bring myself to putting an LS in it as it just didn't seem right. The Mod motors or Coyote would have been nice but I seriously doubt they would have fit.

The best clip I can get is on Mast's IG page, they still haven't given me the harness so I haven't even heard it run in person:
Mast dyno test

Here it is when they displayed it at Holley's Ford Intergalactic Fest:

JB,

Pure music! It will be interesting to hear it once it's in the Cobra. The new headers and sidepipes will probably give it a little more bass which should be a fine enhancement.

You are doing an enviable project.

Tom

Thank you sir, I'm sure looking forward to hearing it rumble to life, I might just shed a tear not gonna lie. I believe the side pipes will give it a very good sound, I mean the 351w even sounded mean with under 300 hp.

I hope to see more of these swapped in Cobra's, there are only 2 others I'm aware of and those were done by professional builders. I'm just a guy in an old barn with no insulation, but I do have a lift and a lot of toys...tools so that helps.
