GM vortec 5.7 replacement long blocks

[Jim K]

Hey guys, I am looking to replace my L31 in my 97 burb. The GM replacement number is 12530282. In the past everybody sold these(Summit Racing, Jeggs, Scoggin Dickey, etc. ). These places are now showing ‘out of stock’. Are these engines discontinued? If not, does anyone know where I can still get one? Thanks.

Thanks for info. I didn’t realize they changed part number.
