Well I was checking a new truck in today and noticed that it had 5.3 Aluminum Block 310 HP on the sticker . I was like WOW. When did this happen?? Our owner said that we had a few out there that had this motor. I ran the vin and it looks like the RPO for the Aluminum block is the L33 5.3 motor. The 5.3 is slowly working on the 6.0..... Come to think iof it will the 6.0 be aluminum???????

 

.... on me here. I have one and have posted on the subject.

 

We can only hope so

 

Man, I was wanting to be the one who broke the news lol Dont know how I missed your post.

 

This is on the 05 SSR it's the LS2:
NEW! Engine, 6.0L V8 aluminum SFI (390 HP [290.8 KW] @ 5400 rpm, 405 lb.-ft.

 

Wonder if it will make it into the Silverado's???

 

I bet it will in the next 2 years.

 

I thought the all aluminum 6.0 LS2 was going in the 05 Vettes and GTO's, 400 HP.

 

This engine would work nicely in a RCSB with a T56 or a 4L80E. I would trade for one.

 

If they put a 6.0 LS2 in a reg cab i hope they take used wives in on trade because thats the only way i could afford another vehicle. LOL
