[Dark_5.0]

A 99-01 cobra is pretty close to a LS1
A 03 Cobra should spank an LS1
A 03 mach 1 should be every bit as good if not better than a LS1.
A 96-98 cobra with gears and exhaust will normally haul ***.
A 87-93 5.0 with a heads,cam, intake package will haul ***.

I beat LS1's all the time in my stock 01' Cobra............I cant beat them all but I hold my own nicely.

My 90LX will crush a stock LS1.
