Question still stands?

Would i benefit more from running the 3.4" and adding timing, maybe 18-20?
Or runing my 3.2" and runing only 16-17* to avoid kr, because of the texas heat?

Reason i'm asking, is because i ran a 13.6@100mph 1.9' with 17* timing on the 3.2" with blips of kr at the track.
If i wanted to trap higher i would have to had added more timing,which= more KR.
 


A larger pulley with no KR will make more power than a smaller pulley with KR. How much KR were you showing with the 3.2?

This is only true to a certain extent. It can go both ways, but if you're overfueling the car to keep the KR down with the 3.2, then you may be better off running the bigger pulley, more timing and less fuel.
 
like brian said, its a matter of how pig ass rich you are on the top end to drown the knock. if youre just knocking slightly becuase you have the correct AFR and youre just running too small of a pulley, youll probably be a little faster with it. i would back it off a little, add timing and see what it does.
