Definitely get the performance series, which I believe you are if it's 565/1850. The performance series comes with the dual line high pressure fuel pump, it's a superior pump to the single line ones that you have to keep a close eye on.

A person could always have an engine tuned for better fuel efficiency if that's what you want rather than buying the efficiency series engine. Just a thought.

I am going to double check on that tomorrow and will update.

I got it swapped to 3.73 plus changed the tranny to Fuller RTLO22918B 18-speed with clutch to 2250 ft-lb, Ceramic, 6-Paddle, Predamper.
