1970 Slant Six Duster

I agree with the disc brakes. I'm putting a 440 into my Dart Sport with 727 trans. Was a /6 with 904. I have researched this out and with aluminum heads and manifold the 440 is only 100#s heavier than the /6. Minimum 8.25 sg. Depends on horse power your going to put to it.:coffee2:
