Take a guess where the bottle neck is!

Are you spinning? What RPM are you shifting at? That seems like it could run mid 13's............... Hows your tranny?

Trans is solid, has a 3K stall converter. It's real lazy with the 3.23's though. I was shifting right before 5K, if I tried to pull it past 5K my times would suffer pretty bad. Tires couldn't get traction all the way through 2nd gear.
