this has a casting part# of 12568952 it's a down tuned LS2 engine with extra steps thoughThe exact same 6.0L motor without AFM is the L96 from the 3/4 & 1 ton trucks. Later motors are also e85 and all L96 are aluminum head and iron block. You’d use the same ECM and simply install a device to turn off the AFM because the L96 doesn’t have that hardware.
It would add about 86-90lb to the weight of the truck though
No wonder they want my engine so badly they want to steal my LS2 block
