gears??? why not

Depends? whats the point in running 4.10's in a stock 5.0 with a T-5 tranny? Might be more helpful in an AOD car but when the stock powerplant makes peak power way down below 5000 rpm you'll be losing out because the engine is all out of gears going down the track.

Build a hot SB that can rev higher then the 4.10's become useful
