12'S shouldnt be a prob,my ss4000 hits hard as hell.11.90"s even with a little weight reduction and some good air. 
How much will this help? ss4k and et streets
How much will this help? ss4k and et streets I'm getting mt et streets this winter and a yank ss4000 stall! My car pulls very hard for a bolt on car. But I do spin alot. I know I'll need the tires with a stall. Think I could hit low 12's or maybe even a high 11?

?????? Im wanting to know also. I plan on doing the same setup. hopefully we will get a answer.
with ~370 rwhp i went from a 8.4 in the 1/8th to a 7.7 with the only change being a 3800 circle d converter and et streets. 7.7 should be around a 12.0 1/4 mile. i think a low 12 would be easy maybe even an 11 if your car is light... my car is a full weight ws6. heavy...
My car went 12.0 with a 1.6 60" before the cam. And that's with 315 nittos and a 2.73 gear with CE adjustables that are probably junk. I'll be switching my 4400ss out this winter in favor of something more practical. Make sure you get a cooler. Traffic is hell with a big stall.

I forgot to add that I have a bit of weight reduction. Removed spare tire and jack, air delete, egr delete, front bumper support, rear seat, no cats, a/c system is out and a few more things I forgot about.

I went from 13.1 with a 2.04 60 ft in -85 da to a 12.5 with a 1.72 60ft in +1428 da with the only change being a Yank ss 4000 stall . If the da was the same I should of went 12.30's . Thats 8 tenths !! Will see better #'s when I go back in the cool air with no sway bar or jack hopefully .Maybe 12.20's with a stock engine ,exhaust manifolds and LS1 intake
