I am happy to report that my 2.7 Heffner pulley is staying in place. Many thanks to Jason Heffner for overnighting a replacement pulley. I have over 300 miles on the new pulley, including a track day, and no movement has been noted, although my neck is sore from constantly looking over my shoulder at it. With ther pulley, Accufab exhaust, Mafia and a 92 octane tune, the car is generating a very enthusiastic 624 RWHP.
