I don't know what this car weighs... but I have lots of broken 727, 8 3/4" pictures I could show you when I only had home ported iron heads, non-pro 275's, and a REAL small cam...

Eddy's, a good cam, and pro's are only going to make more power/be harder on the driveline.

Just based on that, I wouldn't bother even trying the 904. And I also would think REAL hard about putting a Dana in the car.

Just depends what kind of ET you're looking for though.
