Thread: need some help on a bin

I bought a 03 monte carlo ss with a bad l36. The previous owner said that they had goten it really really hot so i went ahead and pulled the heads and it was really bad. So i am in the process of swapping in a l67 out of a 98 gtp i am trying to figure out what bin i should use in the pcm. The l67 is completely stock i went ahead and used the 03 Monte tranny the previous owners said it was good. any ideas thanks
