Skip the JASPER LS reman, it is no good. I have been messing with LS based engines since they hit the F-body in 1998.(technically it hit the Corvette in 1997 but I didn't have one of those) I have had 6 different LS engines. 1 ran 10's the other 2 ran 11's and the other two were trucks.
Jasper is no good with them. I don't know why.
Find a low mileage one at the boneyard. There are thousands of them.
You don't need the D.I. engine. A lot more to swap over.
If you get an earlier one you have to have the reluctor ring on the crank swapped along with intake and various other items from your current engine.
2006 and up use the 58 tooth reluctor ring. It is an easy swap.
There are tons of ways to do it, you could even find a boneyard 6.0 as you have an 09. The 08 and up 6.0 will bolt up to your transmission. (Maybe 07 too, I can't remember off the top my head)
I am currently installing a 5.3 LS based truck motor in an 85 Malibu wagon just like my parents had when I was growing up. Hope to have it running by spring.
