I have a 91 Z28 305TPI the usaual mods I am running 26x8.5x15 M/T slicks and was going to run 4:10 gears and a stall somewhere around 2800 to 3000 stall with 700r4. I don't drive on the street much just race it will that get me out of the hole on the track? And will the car gear out before the 1320?

 

The car will not be out of gear....you do have 4 gears!

What i would be worrying about is that 7.5" rear & slicks.. You may want to make sure the posi is in good shape.

 

The posi is in great shape. Will i notice a bigger gain in the 1320 and will my 60' drop??
