anyone hear of 440source.com?

Great reply moper. Real information, and not just the same stuff that's been repeated over and over. What do you suggest one would do for rods? Get theirs in the kit and resize them, or buy a la carte and get rods somewhere else? What about Muscle Motors? They say they get 313CFM at .600" lift out of a set of 906 heads with their CNC program.
