Hey,sorry i didnt get back to you Mark,Just got home.
What are you shifting it at?

 

[Otto J]

If you are shifting at 6000 and trying to cross the line there.
3.73s should get you in the 133-135 zone in the 1/4

I would say anywhere in the 3.73 3.90 range with a 9"

agreed

Yeah i was hoping to find a set here, a guy has 411 and another has a 488 i think that's too much rpm on that stock block, what do you think cal?
