Best time with the SS3400 was a 7.80 at 88mph with a 1.72 60ft 1900 da.
Restalled to 4000 and on a similar da, car went 7.48 @ 90mph with 1.57 60ft. Was on a MT Radial Pro both times. I was very satisfied.
Mods are BTR stage 3 cam, ls6 intake, FLT 60e, SS4000, Umi tq arm, founders LCAs, Pacesetter headers Y pipe and bullet muffler, jegstars and mt radial pros. 9" with 4.11's and 3650 race weight.

 

That's awesome. I run the ss4000 too and I've always been a huge fan. Really surprised though that it picked up .3.. It's obviously working well.

 

I really think it just utilized the cam's powerband better.

 

Nice run definitley worth the restall. Thats a huge improvement.
