The all aluminum 5.3L you speak of is the L33. It was used in the 03 SSR and ex cab 4WD trucks. It is considered the 5.3L HO. There was also another type of aluminum 5.3L, called the LM4. Its output was the same as the LM7, and it was found in the extended length versions of the Envoy and Trailblazer.
Do you see a pattern? Even though the LM4 is dimensionally the same, has the same output, and has the same parts as the LM7, GM had to change the RPO on the motor solely because of the aluminum block.
So, with that said, there is no RPO for an aluminum block LQ9. The motor you guys are talking about is the L76--like I said before. This motor is the Gen IV version of the Gen III LQ9.
And I win...as usual. Jurt, Ricky...you both have just been PWNED!!!!!!
