I have just finished rebuilding my ls for boost should hit around 400hp (I hope) my question is what tranny would be the best choice for drags I have just the stock ls tranny now would switching to a b16 or gsr tranny benifit me or should I regear the ls tranny? can I regear it?

 

Tire size and RPM for the strip?

 

225/50/15 falken tires on falken rims. The ls tranny just seems to long on the gear I dont even have to hit fourth gear in the quarter.

 

Rpm?

 

LS trans with 4.785 FD
