Spend the extra $500 and get the GMPP 350/290hp version. You will be happier in the long run :nanawrench:

The 350/260hp motor is a GM Goodwrench motor, the 350/290hp is a GM Performance Products motor. IIRC - my balancer was under $150 from GM, the one recommended in all the specs & paperwork that came from GM with the new motor.

Goodwrench is a great motor, wasn't sure whether you are looking for more HP than the 260...
