i wonder why it lost power with a 3.0 pulley...
but a 3.4 pulley certainly wouldn't act the same way with a smaller magnitude, that would actually agree with the laws of physics...
think of it this way bud. if GM could have simply thrown a 3.4 pulley on it with no other alterations and kept the same reliability of the motor, and then marketed it as a "performance" package to a difference market niche, don't you think they would have? especially when the genIII was used for 5 or 6 years? GM didn't build the 3.4 setup because it would have been more expensive off the lot and it would have lost a little bit of the DD value. if enough people bought a 3.4 setup from the factory, something went wrong, like it wasn't tuned right from the factory, and everybody blew their motors, a very popular platform would have lost a lot of sales.
a 3.4 pulley means a significantly more air going into the motor. it's gotta go somewhere.
