Default L33 identification help

K so I realize that the l33 is all aluminum and will either come with 243 or 799 heads but is there any other way through the vin that I can be sure it's a l33 instead of another variant of the 5.3l like the lm7? Thanks

8th digit of the vin should be "B" for L33 "t" for LM7
