Hi folks
What is the best AFR to use for LS1 with LS6 cam, ported LS6 heads (11.2:1), LTH, and 36 injectors. I keep reading numbers from 12.6 to 13.5. What should I try, I know once I get a number, it will changes depending on how well it does.
Thanks
Bill

13.1 seems to be a good all-around number. each car is different though, you have to get a dyno tune to find your optimal ratio

just start with the richer (12.6:1) log A LOT!! and work it from there.
