Awesome Andy,

This is incredible information! Many thanks! Anyone out there building a nice 351W would do well to read your posts.

Next question - These motors are described using Trick Flow heads. Any idea how trick flow compares to Air Flow Research? Summit says Trick Flow is bolt on 78HP. Westech Performance did a story where AFR heads added 75 HP. Both considerably more than Edelbrock or Dart.
