I am very happy with my Butler Pontiac turn key engine - this thing is a work of art. Excellent service from the best Pontiac engine builders in the world. All Butler employees I dealt with always responded quickly to all questions, are very patient, very knowledgeable, and a pleasure to deal with. I would recommend anyone looking for a quality engine to give them a call and see for yourself.
