Thanks to Total Performance on one hell of a build. My 347 is now installed in the car and is completing the break-in tune; 40 miles to go. I plan on putting the car on the Dyno in December for the new racing season. Here are aIMG_0511.JPG IMG_0512.JPG IMG_0513.JPG few pictures of the engine on the stand.

I've seen your numbers, I'll try to stay in your window and not the rear view.
might have to up the power in the SHELBY to keep up now.. Needed some motivation
Haha don't feel so bad, mine gets 8 gallons/mile and is literally unstreetable. So if you get close to it in your street cars that's badass!
