i know it will hum with my 1 3/4 hookers. i just made a point that it sucked back the gas, and it was annoying at best! scorp would you agree that the 4+3 is better for topend then the ZF6. Meaning the 4OD is better then the ZF6 5th gear because of the ratio. BTW, Did you ever get your car tuned?

4+3 4th/OD = 0.68 or 0.60
ZF6 5th = 0.75
4+3 rear end = 3.07
ZF6 rear end = 3.42
Final for 4+3 = 2.087 or 1.842
Final for ZF6 = 2.565
The 4+3 has a theoretical higher top speed, but the ZF6 is going to pull theirs easier in most cases.
*edit*
car not fully tuned, life is too busy and needs a fuel pump.
