3.09 4 Speed Gear Set Strength

I put that gearset in a b body transmission that was used with a solid lifter 440 in my brother's '69 Charger and then in a '64 Polara. It took dragstrip abuse with slicks with no problem. The ratios are similar to what many stick drag cars use in a Jerico 4 speed or a G-Force G101 4 speed.
