I ran 11.75@119 with one of the 1st 1.5L KBs in a full weight 91 GT. This one did not have the bypass or the GT40/Flowzilla setup.
stock shortblock -including cam
Edelbrock 6037's w/1.7 rockers
Holley Systemax I (no longer made)
42lbers, 90mm LMAF, KB chip
Centerforce was slipping, or else I know I could have gotten 11.5's out of it.
1.58 60ft with a 2500 rpm launch...

TORQUE!!
They are nice street SC's but if you want all out track times or dyno #'s get a Vortech, Paxton, or ProCharger.
