My setup is a lq9 with a gm hot cam, FBO, 3k stall, with 3.23 gears.
Previously with the 78MM intake and 31" street tires it went 13.5 @ 101 in 1900 DA
Added a 90mm tbss intake and tb along with some 28" DRs it went 13.0 @ 103
actually a SOTP difference with the new intake setup.
4.10s and 243 heads hoping for 12.5s

 

That's damn good with the highway gears. How much faster was it at the 60' mark?

 

what did your 60 foot look like?

 

With the gears being so high it actually 60' the same with 31" street tires and 28" DRs maybe the high DA played a role in that.
1.9 both setups consistently.

 

you picked up 2 mph nice.
