Why not a filled 6.7?

trying to decide if I want to switch over to the 6.7 block, currently I do not have one

If you want tried and proven do the 5.9. I agree with fairallbilt. However, if you want to absolutely push the limits go for the 6.7! Subscribed, I want to see this!

my main concern is the strength of the 5.9 block after being bored that far
