Ordered engine. Free delivery a month later(after build). Had plenty of questions. Alan at Pace Performance was more then helpful. Engine Dyno sheet shows more power then wat it is rated at :D 525lbs torque!! 502hp!! :) Installed it in my 87 5900lbs(with me in it) irocZ.Started right up! Great oil pressure! Power feels amazing! I am veryy happy with my purchase... FYI- The EZ-EFI (base system) that is sold with the engine does not come with the hanheld controller.
